AFTERPAD

I want to say that it is inserting the Horipad right at the top of the list with the Mad Catz. If you're interested in games that require a d-pad, it's the best you can get aside from the Gamevice.
I'd also recommend the Micro CTRLi before the Stratus XL. It's small, and it's clip sucks for iPhone gaming, but it's still a solid controller for iPad gamers.
