How much are you willing to spend??
Top: Reconyx, these are the best of the best but you get what you pay for.
Ive also used:
DLC Covert: runs around $200 in my area. the battery life is unreal! and the picture quality is above average, also comes in IR
Moultrie D-50: $100 .. It was a really good camera for the money. didnt have IR though.
Bushnell Trophy Cam: $200.. IR and took really good pictures day and night, however, the cam started to bugger up and started taking pictures that were half day/IR during the day after about two weeks, I most likely got a dud but i wont be spending that kind of money again with things like that happening.
