You might be getting ahead of yourself if you don't have any experience with trail cams and you intend to buy 4 to 6 right out of the gate. But hey, its your money.
I did a lot of research before christmas, including reading tons of reviews on cabelas and bass pro shops websites, and I ended up getting the Primos Truthcam 60. I bought primarily based on the reliability and features, with a price limit below $200.
Another thing to consider is the likelihood of theft. I based my purchase also on the availability and quality of lockboxes for the trail cam, which varies greatly for different models.
I am very happy with the camera so far. It takes good quality pics day and night, is very easy to set up. With an 8GB memory card, it is impossible to fill it up on one set of batteries. One set of batteries take about 3000 pics. The lockbox is rock solid; in addition to screwing the box to the tree, I used a chain attached to the padlock and wrapped around the tree. No one is getting that camera without some heavy duty equipment.
