A.S.
Hi! My name is A. and I purchased my camera for similar reasons as you. I got an inexpensive Philips PC camera. I got it at wal-mart for less than 10 dollars. it plugs into a usb and has a clip on the base. The base has a 'socket' joint so you can also rotate the camera in any direction. pretty neat for a cheapo. lol
hope this helps
