I use a digital trailmac that uses smartmedia cards (new ones have Xd cards, I think). I think the newwest versions use olympus d-390 2.1 megapixel cameras. They have color lcd screens and if you get an extra memory card you can just swap cards and brig the card bak home and download them on the ' puter. It uses 10 AA batteries total and in warmer weather they last three months or so depending on how many pics are taken. There are several other digitals out there. Camtrakker and deer cam make one, I think. If you want to print pics out, then make sure you get one with a good resolution, some of the cheaper ones have low res and grainy pics.
