I've had a Canon S30 (3.2mp), great camera until I took a spill crossing a creek in CO, myself and the camera got soaked, I recovered, camera didn't. I replaced it with the newer S60 version (5.0mp), great camera too.
I suggest going to
www.cnet.comand read some reviews and users opinions. I never buy any electronics without checking there first. CNET will also show you the cheapest place to buy.
