Not the cheapest webcam on the block but definitely one of the best for stop motion animation at least in the non professional field. Combine the  Carl Zeiss® optics and improved wide field of capture this makes for a really good animation webcam. I notice alot of the good brickfilm makers especially have noticed the benefits of the Pro 9000. I always personally prefer to use a clip on type webcam (normally designed to clip on to the top of your LCD screen) as their small size and clip allow you to connect the webcam to anything in confined spaces. Here is a good example of someone using the Pro 9000 from NickMOCstudios
