For a quick, inexpensive, but very nice solution, I'd recommend TPU-cases.com. There's a couple threads in this fourm about them, with some pics and user experiences. I think he's out of the matte black right now (which I use and like).
I picked up the carbon one from sprint to use while I wait for my tpu case. The carbon case gets it done, but the edges are so sharp I could rename it the ginsu case. Definitely going back once the other one shows up
