here is an article from the article section. Not a lot of information, but reasonable.
My first recommendation is Battle Foam. I have the 1520 (or whatever the number is) and have no complaints. Friends of mine have the 720 and enjoy them as well. 1 player has the Sabol Army Transport case and the Battle Foam and has said that he wishes he'd just waited and bought 2 of the 720s.
But, there are plenty of cases out there and people will be sure to tell you their favorite.
There are plenty of threads on this topic. You might find your answer there, too.
