Best iPad cases?

So I need to buy a case for my recently purchased iPad 4th generation. I don't know what to buy so I was hoping that the Apple Core could help me out!

It has to be moderately strong. I'm going to drop it at some point I'm sure, but I'm not gonna run over it and I don't need military-grade protection or anything. It would also be great if it came in different colors.

Thanks!
