I'm sure there are a ton of good cameras these days. A few years ago I did some research looking for quality (inexpensive) cameras, and ended up buying Covert cameras.
They are pretty nice little cams. Good picture quality, small and compact, still or video options, and they come in infared or black. You can find them for under $100. My newest one is 2.5yrs old, has taken over 20,000 pics on its first set of 8 AA batteries - and they are still in it. That is being out in the woods from July to around end of Feb... through the bulk of 2 super cold winters.
