Aaron!

I recommend the Canon PowerShot S1 IS.  It's a regular digital still
camera, and one of the few w/ "real" video.  It's limited to ~ four min.
/ clip *.  Plenty for "our" purposes.  It's a basic 3.2 megpix. 10X
optical zoom camera, and image stabilization!  I haven't used the
bundled video editing ** , but has some effects (brightness, contrast,
sepia, etc.) in addition to what one minimally expects in editing.

* This is w/ 640 X 480, 30 fps (close to S-Video? ) and low
compression.  One hour possible at lower resolution and huge (one gig.)
card.

** I use Premiere and, of course, imovie.

bc

p.s. don't pay more than $400
