I have a few older coverts that work pretty good, but I hate the stupid remote I have to use to program them.
A few years ago, I bought a few of the bushnell trophy cams and have been very happy with them. You have to be careful which model you get since there are like 13 different models with "Trophy Cam" in the name, and some work better than others.
I have a few of the 11-9636C and they are awesome. I use 4 lithium energizers in them and can get a full year and literally thousands and thousands of pictures out of them, the detection zone and trigger speed are phenomenal, recovery is fast, and programming is very simple. I also love the compact size so that its not a huge burden carrying 4 or 5 of them out at a time.
As someone else mentioned above, check out trailcampro.com. They have awesome reviews and tests.
