I use Moultrie. You can get a W35 for about $45 bucks or so with free shipping from ebay. They have never let me down. Take good pics and do not break the bank. There are far better ones out there but cost way more ($200 or more) plus you have to worry about getting it stolen on public land. With SD card, batteries and lock (Master Python) I am in about $100 for each cam. Absolute necessity as far as I am concerned as you will get a lot of night time pics as the deer switch to becoming more nocturnal as hunting pressure increases. For me, it is a must have tool much as OnX is. I dont think I would be as successful locally on public land without it. Period. I can see if there are bucks in the area, and generally gives me a good idea of the kind of bucks, whether spikes, forkies or larger. If none, then I can move on.
