Ampahunter, I'm very happy with the the trail ghost. I use the P41LE unit, which is $399.00, I believe the P41UNI is $420.00. www.trailghost.com/2.html
They both use the same Sony 4.1 megapixel camera that Penn's Woods use in their high end cameras.

Teejay, I still do my scouting on foot, but trail cameras are a nice hobby. It's kind of like fishing, throw the bait out there and see what you can catch. My kids love going out to check the cameras to "see what we caught". I have caught several trespassers and know what time of day the Turkeys come into my clover. I don't have the time to sit outside from sun up to sundown everyday to keep notes on when the animals move.

You still need to scout the area and look for sighn, In fact I usually do this prior to setting up a camera to determine if the location is even worth it.
