Hello, I recently purchased a new Mac Pro. I would like to get a good quality camera for it. Since Apple no longer sells the iSight, is there a way to get a reasonably priced camera that will work well with iChat/Photo Booth/iMovie? I am currently using a USB camera (the Xbox Live Vision Camera) and it works alright, but generally has poor performance. I have been looking at bids on eBay, but iSights normally go for around $200 US before shipping. Is there a cheaper alternative that delivers good performance, or is the iSight the only way to go? Thanks.
