There are some you can find but you have to download drivers for some, or get programs to adjust settings, etc. I have a Logitech Quickcam Zoom (pro? i dunno) and I had to download a program to make the image from a dark screen to actual picture. You can download a program (around $10) iChatUSBCam that allows USB Cameras to work with iChat. Otherwise it works fine with everything else you need it for. If you want a good quality camera don't get a cheap one. They don't seem to be as good, and try to stay away from USB 1.1
