so what kinds of prices are we talking about and what kinda resolution do you get with these cams that run about 30 fps?
It will do 30FPS at 640
~$40 dollars with microphone and both mounts included in box. It will do megapixel 1280 snaps (I think - at least 1024).
Check out my moon pick in the modders folder (Astronomy mod). That a still shot and video frames are similar. And I reduced the res and color for the forum.
Logitech Quickcam IM
If you want to go even better, the logitech pro 4000 is the best ($100)
and I hear the Logitech orbit is nice (same CCD as the IM I think - but it has fancy tracking stuff for vid conferenceing - ~$100)
