I just put two cameras on order for $6.99 each from http://www.aiptek.com/. Check page 3 of their on-line -catalog'.

I have no idea about the quality , and I'll probably eat through 2 AA cells each time I pull it out, but it looks small and light and I've read where you can short the shutter switch to fire it off instead of rigging a servo to press down on the shutter button.

Just thought I'd pass that out.
