Purchased the SmartShell iPad2 Case from Speck. Well finished polycarbonate. It has picked up a few barely visible scratches in the month I've owned it, but that's what it's for. At $34.95 it's toward the top end of scale in terms of price.
But what set it apart from the competition is the embedded magnet in toward the "bottom" of the case. This holds the Apple Smart Cover in place nicely and eliminates the "floppy" cover problem. All in all, that feature alone was worth the purchase.
