Well, I set 3 cameras out on my land I'm buying 2 weeks ago to see if I could get any pictures. A Moultrie Game Spy 200, a Stealth I390 and a Bushnell Trailscout. I was pleased with all of them. The Moultrie has a solar panel and took 200 pictures and the battery status went from 94% to 99% during the 2 weeks. The Stealth only took 56 pictures, but actually took most of the best ones and the 6 volt battery showed to still have a full charge. The Bushell took 1,448 pictures in 6 days before the battery went dead. I made a big mistake setting it up and it took pictures of a fence post blowing in the wind about 1,400 of those pictures had absolutely nothing in them.
Here are a few of the best pictures from each:
Stealth I390:
Moultrie Gamespy 200:
Bushnell Trailscout:

(I would have never guessed that a cow could have made it under that fence - 99% of the rest of the pictures were exactly like that picture except without the cow - that fence post must have been enough to trigger the camera)
I moved the bushnell to a new spot. I was really excited going out to check on them and was very happy to actually get some pictures of something besides a bunch of cows!
