I’ve had a chance to try out the Blue Microphones Eyeball, and it’s a pretty good webcam.  Blue Microphones has just recently announced the Eyeball 2.0.  It has the same basic design as its predecessor with a retractable camera lens and big microphone, but includes a higher-quality lens and 2-megapixel camera.  It is available now for $79.99, but you can get it at $56 from Amazon.
