That page works only if you have selected a country where Sling has a store. I just selected USA and it works OK, showing the IR Blaster at $19.99. The UK page doesn't have it displayed, so it looks as though the USA is the only place to get it. Might be worth going on E-Bay and trying for a third-party one. As far as I know the IR socket on the Slingbox is 3mm, but an not 100% sure.
