My cheap August case (
http://www.ebay.co.uk/itm/2211652726...84.m1423.l2649) is perfect, nice and light and the magnet is easily strong enough to keep the case closed when not in use, available in beautiful colours too. I definitely prefer it to the official case as it is much lighter, (helpful as the PW itself is already quite a bit heavier than my previous reader), and of course the low price is a nice bonus.
