I would suggest a Trail Watcher from trailwatcher.net, either the 4040 or 4060. The 4040 imprints the date and time whereas the 4060 does not.

I also agree with IL-Cornfed, that the CamTrakker is a nice camera but I still prefer the Trail Watcher. Both use Sony cameras but for a 6mp camera I prefer the unit used in the Trailwatcher. It has a stronger flash and the colors are a little more brilliant. The Camtrakker is also a little bit like a jigsaw puzzle to put together, but I hate to bust the Camtrakker too much since it's still better than the major manufactured cams.

The TrailWatcher is real simple to set up, compact and everything is right at your fingertips as soon as you open the case.
