I also have the Moultrie I-40 and would recommend it to anyone. It takes great pictures and lasts a long time on the batteries. In my opinion infra-red is the only way to go. I've seen results from flash cameras versus mine on the same property and the infra-red ALWAYS has more pictures. I bought one of these for my Moultrie and it locks the camera up to the tree very well. It wasn't expensive either.
