Any reason why you wouldn't want to go for an otterbox besides the price? I have the commuter series which is significantly less bulky than their hardest ones and I have had nothing but a great experience with it. it doesn't cover the screen but it leaves plenty of room to put a protector on. At $33 its not so bad.

If you really don't want to go for an otterbox look into case mate, they are another case company that i used and their cases work great as well, for lower the price. However i think they only make back to the g3 now... Those are the two cases ive used and they work very well. IMO go for the commuter, it isn't as excessive as you would think and $33 is not too bad for a case with a lifetime warranty.
