I love my Industriell cover, got it for $29.95. It notches into your Nook so you don't have those bands around the corners. It's comfortable to hold and will easily fold back completely to read. The inside is a nice dark gray shade so I don't have to worry about getting it dirty like with some of the lighter covers.
The only downside, it did make my Nook heavier, I put it on the scale and with cover my Nook weighs in at 1 lb 1oz.
