I have now tested a dozen digital scouting cameras and I know how frustrating it can be. With many of the cameras you never know what you are going to get each time you go to collect your pictures, but do not despair. They are not all that bad.
Take a look at
www.woodlandspycam.com. I have one and overall it is the best one of the twelve. I believe they have some new ones coming out soon as well.
The Penn's Woods that I have is a good one also, but it is more expensive.
Don't give up yet. Even after several of my twelve giving me headaches I would not go back to 35mm. Once you get a good one you won't either.
