My 2 local GameStation's where selling the PlayStation 3 Eye camera for £7.99 each today. Both stores had like a cardboard advertisement of the PS3 pre owned accessories and one of them was the PS Eye cam for £7.99. I never had my phone on me at the time so I was unable to get a picture. They had stock as I could see a few behind the counter. Am guessing this is nationwide judging by the advertisement but am not 100% sure.
Good quality camera perfect it you plan on getting a PlayStation Move controller. Or even if you want to use it for video chat or even for a cheap microphone to chat online. Also works as a normal webcam and microphone for PC's.
