Go to the link below and get the refurbished Logitech Quickcam Traveler for $49.95 (I have bought three of them to date for myself and other people) ($149.99 new at CompUSA) It is refurbed by Logitech and is really a great unit that can also be used as a still camera.
If you do get one of these be sure and download and install the new software from Logitech.
This is a very good retailer also.
