I bought a "Crystal case" (Rubber/plastic composite) off of ebay for $7 -search HARD TPU GEL SKIN CASE
it's great!..... after I took an exacto and trimmed around the button impressions although some may like the protruding rubber buttons.
low profile, good feel, great firm fit unlike the soft silicone cases, excellent protection, feels like I can toss it around without regard
Update:
For my second one today (smoke argyle other one is gloss black). Only button necessary to cut out was camera as it inhibits the two stage press. Power and volume are fine as is
