Check out the Mini Cam for Skype from USRobotics. Having received the certification from Skype itself, this camera functions very well with video related features of Skype such as pre recorded video messages, live video chat and still photographs.

It is a 1.3 megapixel sensor capturing thirty frames per second and gives good results in case of dim light and is programmed to provide proper focus on the face of the individual. This is a slim camera so you won't face any problems attaching it either to your desktop or laptop. This camera would be available from the month of January along with a microphone headset for only $40. Not a bad deal.
