I've tested two versions of the Moultrie and they have both been the worst or near worst of the 13 that I have tested. From my experience I could not recommend them.
For a cheap unit you may look at the Wildview Xtreme II. I've only been using it for about three weeks but so far it is useable for a camera that costs only about $100. I do not know how well it will perform over the long run. I've had the original Wildview for about 6 months and one of the switches seems to be getting a mind of its own. These scouting cameras are cheap and are made cheap.
I'm currently buiding a digital scouting camera myself and if you are interested you could build a real nice one for $250 or less. Building your own isn't for everyone but if you are interested take a look at

On the other hand you can buy a real nice unit for a little more than $400 and I think Pixcontroller has one for sale for about $300.
After all of this wind, my advice is to build or buy a good one.
