With one exception you can buy ANY Slingbox. Although Sling don't like to acknowledge it, all the new Slingboxes can be used anywhere, NTSC/PAL is only relevant if you decide to buy a Pro-HD as that is the only one with a built-in tuner. Don't touch the Pro, it is not compatible with some mobile players. And the 350 has been replaced by the M1 so you won't find that anywhere. So given your suggested choices of 500 or Pro-HD, you can buy the 500 anywhere or the Pro-HD in Europe to get a PAL tuner.
Looks as though my short list is the "SlingTV" "Sling 500" and the "M1" in that order , the SlingTV is the new 500 model which is a 500 with new generation software although a 500 with new software becomes SlingTV .
The M1 is the 350 replacement which is faster and wifi . Will keep you posted on what I get in Hong Kong and what's available at what cost and where .
The article below is the most up-to date I could find re Slingbox Media , written this year in the US going by the prices.
Sling Media on Tuesday announced an update to its Slingbox line of devices and apps, including a new entry-level Slingbox.
Slingbox, for those that have never heard of it, is the original "TV Everywhere" device. It connects to your cable or satellite box and lets you access that TV signal from a computer, iPad, iPhone, Android tablet, Roku or Apple
The newest member of the Sling family is the Slingbox M1. Retailing for $149, the M1 replaces 2012's Slingbox 350. Not only is the Slingbox M1 smaller and faster than the Slingbox 350, it also comes with integrated WiFi and Ethernet.
If the cable or satellite box you connect to the Slingbox M1 has a built-in DVR, you can access the DVR and playback or schedule recordings remotely as well.
Sling 500 gets rebranded SlingTV
In addition to the Slingbox M1, Sling has decided to rebrand its flagship Sling device, the Sling 500 as the SlingTV.
The SlingTV is the same hardware as the Slingbox 500, but it has received a significant software update. The new software overlays a new on-screen TV guide on-top of the interface. The guide includes content recommendations, Rotten Tomatoes ratings for movies, filters for content currently airing, movie and TV episode guides and even real-time sports scores.
Sling says the idea behind Sling TV is to turn your existing TV into a smart TV, without having to pay to upgrade. The SlingTV also includes a selection of third-party streaming apps, including Dishworld and Blockbuster On-Demand.
If you already own a Slingbox 500, don't worry — your unit will get a free software update to make it a SlingTV. The SlingTV retails for $299.
New and improved Sling apps
In addition to the new devices and user interface updates, the Sling team has overhauled its mobile apps. The new Slingplayer app for iPhone, iPad and Android now lets customers set up a Slingbox M1 directly from their phone — no connecting to a computer required.
Slingplayer for iPad also now supports the Roku and Apple TV set-top boxes. The hand-off process is now even better — with the Roku or Apple TV handling video playback (a la the Chromecast), which means you can close out of the app on your iPad.
I've spent some time using the new Slingplayer for iPad app and it works great with both the Roku 3 and Apple TV.
Using a Slingbox with your Apple TV or Roku will effectively extend your cable or satellite box to another room of the house, or a vacation home. Slingbox plus Apple TV is a great way to save on cable. Just pipe in the content from your cable setup at home and enjoy it remotely while on vacation.
Sling has also listend to customers and brought back the free Slingplayer app for PC and Mac. For now, the new desktop app only works with the Slingbox M, but it will be coming to other Sling devices later this year.
The advantages of a native desktop app: users have more control over video, there is less memory overhead and the overall experience just feels more stable.
Almost the ultimate TV box
Sling's target audience are users who haven't cut the cord, but still want the benefit of being able to login and watch TV or DVR content from a different location.
The only real downside to the Slingbox is that that's all it does. It can't quite compete with a streaming service-rich Roku or Apple TV on its own.
In a perfect world, the Slingbox would do what it does best — offer free remote access to your cable or satellite box — while also offering a way to access streaming content at the same time.
The SlingTV almost fits that mold. With third-party app support, such as Blockbuster, the potential is there. Now if only we could get Amazon, HBO Go and Netflix on board.
For users that want an easy way to access TV no matter where they are, or who want to extend their cable signal to other rooms on the cheap, Slingbox is still a great device. If Sling would also support Internet streaming services, the appeal could become universal.
OK. Be careful of the term "Sling TV". There has been a monumental ****-up at Sling in that just after renaming the 500 as Sling TV, a different area in Dish/Echostar announced "Sling TV" as a new streaming service to rival other TV services. And this has nothing to do with the Slingbox 500. Classic case of right-hand not speaking to left-hand.
I always hesitate to make recommendations, but I have a 500 and and an M1 so feel in this case I can . Obviously the 500 is more capable than the M1 (and more expensive) with an HDMI input and the ability to interact via the TV screen, with some smart apps, but in my case I cannot use the HDMI because Sky UK have implemented HDCP to prevent use of the Slingbox unless you buy another third-part box to strip out the signal, and I see no real advantage being able to control (NOT watch) on a TV). So my favourite is the M1. It has one disadvantage in that you cannot watch in a standard browser and need a dedicated viewer application, but as long-term user who much preferred the old Desktop player to the browser player, I don't see that as a problem. But this is very much a personal opinion.
I live in Australia and travel to Hong Kong and want a Slingbox in Australia . Slingbox Australia Facebook page shows the 500 but not available and don' t have stock of the Pro and no mention of the HD . The U.S. has the 500 is this available in Hong Kong or Australia . Or do I get a 500 in the US and change my set top box in Australia to NTSC instead of the PAL system .
Please advise what is the best Slingbox to get in Hong Kong or Australia , seems to be a lot of confusion on models available in different countries , don't want the 350 or pro just the 500 or Pro HD?????
Please advise as Australian Slingbox site and office is useless.
