I have used them all and the best bang for your buck is one of the Original trail cams the camtrakker. They are built right here in the great US of A and work better than any of the others on the market! They are worth the $429 since they come with rechargeable battery packs have super crystal clear images and can detect motion much farther away than other high end cameras. I place them on intersections in the woods where trails cross at different distance like out to 60 feet and farther. Never miss a shot. Check them out at
