Ask Kwhizz what he uses. Small, great resolution and obviously TRIED & TRUE.
I have a three year old Sony Cyber-shot....5.1 Mega Pixel with a 1 GB Memory Stick.....Small, Light, Cheap, Battery lasts forever, and never came close to filling the Stick up even when shooting video's along with Pic's......Point and Shoot......Easy enough that even I can do it......(No Talent Required....LOL)
