I'm just finished with the setup on my new Slingbox 500 and Motorola VIP1853. I struggled a bit with the location and ZIP codes setup because I do not live in neither US or Canada. The most difficult was to find the right remote control, but with good help from this forum I also managed this.
I can recomend the Zaptor model under Motorola. It works perfect for me
