Does anybody here know wherabouts I can get one of these?

About a year ago I had my eye on one of these;
Buffalo PC-P3LWG/DVD-1
Which allows you to stream video wirelessly from your pc to your tv, but I can't find any of them now. It was a decent price but now it's completely disappeared and nobody else seems to make things like this and Buffalo have infact stopped making them.

I live in a uni flat with 4 other people and we have a TV I would like to use the wireless on my pc to transfer video etc. onto the tv.

Any help appreciated.
