I got the isight for my ibook. I spent 2 months deciding on which webcam to get. I am very happy with it, very good picture quality (for a webcam of course)... Im not really sure about it, but its probably one of the best quality wise. Then again you can always use a DV camcorder for chat, but thats larger and more expensive. As for the isight, its worth the 150 IMO...
