Man I use a Leaf River Trail Cam. I change the batteries maybe twice a year. I keep that thing out all the time. Basicly all of deer season and most of the spring. I got it last spring (a year and a half) and I've changed the batteries twice. You should really look into getting a Leaf River model. They're like 150 bucks. Never had a problem with it. Good pics, always works, simple, and many choices. My is not digital though.
