There's only one way to find out, guess I would try one of these:
http://www.currys.co.uk/gbuk/r/logitech%20c270/0_0_0/
in stock in MK, or if you want to spend more the microsoft hd cams can be found for £35 online. better quality the picture, bigger file to capture etc.
sorry cannot be more helpful, seen your other post Matty and no one else is replying, what you need is to borrow one, must be someone with something, I think Truman uses a camcorder when streaming.
