Autofocus is essential (IMHO). The "Flex arm" cameras are not great - hard
to focus on the projection when the image is not stable. We have used a
couple of AverMedia cameras (CP150 flex arm, 300CP, now SCP300) and what I
have seen is that the less expensive cameras are not as good at auto light
adjustment/white balance. Zoom feature is nice, but "jumpy" on all.

We settled on the SCP300 (more expensive) due to feature set and image
quality (esp. auto white balance/light adjustment). Form factor is great:
arm folds in for upright storage or flat. Camera head tilts up for webcam
use. Solid, heavy base makes it a very stable unit. Good software package
(we are just beginning to delve in).
