I was waiting for the Musubo cases to come out, but decided to pull the trigger on the PureGear Slim Shell instead. I ordered the Black Tea one from this seller on eBay: http://www.ebay.com/itm/PUREGEAR-SAM...item2573f30cba
At $22.75 and free shipping, this is the lowest price I was able to find. It's out for delivery today, so I'll post a quick review within the next couple of days. I'm currently using a CruzerLite TPU case, as I'm not a big fan of dual layer (i.e., Otterbox, Ballistic, etc.) cases. The PureGear certainly seems like an interesting option.
