Knute, If you are looking at stealth cams stay away from the 3.0mp camera. A few of the members here have had some issues with them and I'm sure they'll chime in in a bit. I've had good luck with the stealth 1.3. I get 20 days from a set of 6aa batteries. I use rayovac I get at walmart for $7.00 a 24 back. Pic quality is good and the cam is easy to operate.
Cuddleback make a great digital which is a bit more exspensive. Maybe double creek can give yu more details on the specifics of that cam.

OR if you're handy like that, You could build your own. I'm pretty convinced that the next cam I get will be a home brew. If your interested in building your own do a search on homebrews. T in PA is a wealth of information on the subject. I think a homebrew is pretty tough to beat in more than a few ways.

Hope this helps some
And Welcome
