Seidio Active case. Very similar to the otterbox commuter, but a hell of a lot nicer looking in my opinion. Got a combo kit on Ebay for $40

Also comes with a very sturdy holster.

After using the commuter for a day.. I think I should have gotten the Seidio Active because it looks like it has better gripping. The commuter is pretty slippery.
