RE: Help with ideas
I know what you are going through trying to choose a game camera.
In my opinion your $150 limit is going to make it difficult to get everything you want. I also agree that digital is the way to go. 35mm cams are quicker but have many drawbacks.
Setting up the camera at a water hole will help but some cameras are much more reliable than others and flash quality varies considerably. You are looking for a good quality reliable camera with good battery life and these game cameras are available but will cost more money. Another slightly cheaper option is to build one yourself.
You can take a look at our digital game camera reviews at our website listed below. We've tested 19 to date and put out our latest homebrew this weekend.
