I don't want to spend to much I have found this has anyone else got this??

Thanks,

You could of course spend 500/600$ on the Cthulu card from Nvidia, the one that does wireless video. It's only a GTX 460 though, but it works like a charm. Otherwise, I think there are streamers for short term, line of sight problems.
