Ive messed around with a few trail cameras. The best I've used, by far, is the Bushnell model 119405. It has every feature I need and the batteries last for a long time (AA's as opposed to the other ones which used 6v batteries which in the cold could only last a week). I left it out for about 9 months once (actually thinking that it would have been stolen or in the least the battery flat) and it was still taking photos… cant get much better than that!
