If economy is more important than top-quality video, the D-Link VisualStream USB PC Camera DSB-C110 ($29.99 direct) might be for you. The VisualStream offers 352-by-288 resolution—provided by a 0.2-inch CMOS sensor—and manual focus, and it comes with ArcSoft's PhotoImpression and VideoImpression. While it's also a desktop cam like the Logitech QuickCam Pro 4000, the D-Link unit doesn't include a microphone or a button to take snapshots. Of course, it also costs about $70 less than the Logitech model.
