I have 2 Moultries, the basic black model which runs $99 is nothing but junk! It takes a 6 volt battery which usually last about a week, even with a rechargable battery it sucks!
The other Moultrie I have is the 6.0 IR, it takes 6 D batteries which last around 3-4 months but for $300 it's over-priced about $100.
The Moultries that use the 6V battery are the models they used prior to 2007. And I agree - they were junk. However in 2007, moultrie changed all their cameras to six D batteries which substantially increased the amount of time the batteries lasted.
I currently have 11 Moultrie cameras. The batteries usually lasts 3-4 weeks depending on the number of pictures. But most of my cameras take a lot of pictures (400-600 per week).

I am surprised no one has mentioned Scout Guard cameras yet. They seem to be the cameras getting the most press right now. I plan on getting 2 soon to try them out. I think they retail for about $200 and do have IR.
