CaseCrown iPod Touch 2G 3Gen Polycarbonate Glider Slim-Fit Case (Blue Sapphire)
The case is very durable and has saved my iTouch from many drops.  My only complaint is that if you have a screen cover, it has to be lined up just perfectly.  Otherwise the case pulls it up at the corners.  But I recommend it to anyone who drops there iPod A LOT!  Great value!
