If price is not an option, then I would go with the Cuddeback. Got a 1.3 and 3.0 out right now. Both have a 2GB compact flash card and it runs off of 4 D batteries. I usually get about 1000 pics off of a set of batteries, sometimes more. Here is a good site to find out everything you ever wanted to know about game cams....
