It seems my cover is not yet covered in this thread.

I have a black "SLIM LIGHT MAGNETIC CRAZY HORSE COVER CASE":
http://www.ebay.com/itm/SLIM-LIGHT-M...item35c82ea17d
It was $9.90 plus $2.90 for registered mail (optional). The quality is acceptable, it looks very nice and it fits perfectly. Getting the PW is also quite easy. The best part is the weight, just 73 grams. The sleep/wake function works perfectly. It folds over nicely but the magnet is holding it only when closed.
Recommended, especially for the price.
