Trail Camera's

So this next year, I'm looking to buy 2-3 Trail Camera's. I kinda like the Moutlrie camera's. Is there a big difference in getting the 880, over the 550? I was first looking at the A-8, but found out it doesn't take video's. What kind of Trail Camera's have you guys had a lot of luck with? I want one with a Moon phase symbol on the picture too.
