I'll put in a second vote for the Canon s3. Although I have to admit that I JUST got it so I really haven't put it through a lot of testing. Some of the reasons I went with the Canon: 1. uses AA batteries instead of proprietary or more unusual types which could come in handy if out traveling and need new batteries in a pinch. 2. uses SD memory card which is a more universal card then something like the memory stick that goes in only Sony cameras. If I match up any new trail cameras properly, I can take my Canon camera to the field with me to use as a card reader. (My current trail cam uses compact flash, but fortunately has its own LCD screen for viewing in the field.)
Go here to find a good website to sort out all the choices. It really helped me.
