I own a Mac Pro and for me as for the most of you, the only option is the iSight Camera, which unfortunately doesn't get produced any more...I bought one from ebay for lots of money... Logitech now has the Quickcam Vision Pro for 99$. In Europe you can find the camera for 60-80€. My new camera came on Monday. I immediately installed it (connects through USB) and I started iChat. What I saw was a great quality difference to the iSight. The picture quality is great, auto focus works very well and especially under bad lightning conditions the picture remains quite bright. Photo Booth works great and so does Skype. The frame rate is at least as good as the iSight. Overall I am really happy and I will sell my iSight. Mac Pro users if you need a great Web Camera, buy the Logitech Quickcam Vision Pro for Mac!
