Newegg has the Logitech QuickCam Pro 9000 Webcam for $60 - $15 rebate [Exp 10/30] = $45 with free shipping. Features Carl Zeiss optics, autofocus, a maximum image resolution of 1600x1200, 2.0 effective megapixels, and 30 fps to keep it all running smoothly for those long distance relationships.
Nice camera. We own three. Skype recognizes these instantly.
But you'll never get 30 fps on Skype. In the best of circumstances, MAYBE 20 fps.
And 1600x1200? Not in this lifetime.
Still, the best I've used for Skype video chatting with my son in England.
