Query: Great little cheap webcam

I bought this camera to use on a Mac. The software that comes with it is not Mac friendly but you can download "MacCam" software for free. If you want to use it for iChat, you can buy a program called "iGlasses" that allows you to set brightness, color, etc. The picture quality is quite good for an inexpensive camera. I would recommend it.
