If you guys aren't in a hurry, or are wanting a few extra cases, you can buy these Cafel cases on ebay for $4 shipped per case. I found that the eBay case was actually more grippier than the Tozo case I originally was using, as it had the textured back, and had much nicer cutouts imo.

Bonus: If you don't care about the flash hole cutout being two individual small circles, this case is identical except it has one oval cutout for the flash. It's $2 shipped per case:
