Not sure where to put this as it dose involve xbox 360 and PC.
Anyhow rmember about 4 years ago Microsoft brought out them Xbox 360 wireless gaming receivers for the PC. It enabled you to use your Wireless Xbox 360 controller with your PC. I built a cheap as chips desktop last night out of spare components I had in storage. Anyhow its good enough to play games like Left 4 Dead and Portal ect. I only have a spare wired mouse and keyboard but I was to sit on my couch witch is to far away for the mouse and keyboard.
So I want to buy one of these receivers. But I can't seem to find a official one anywhere. Amazon seem to be the only place selling the official ones but want £15 for it. Witch is a little steep in my view. I would buy one of them fake ones from ebay as there only £5 but they said dose not work with Windows 7 64bit. I have Windows 8 64bit preview installed so am guessing it wont work on that.
