I recently bought the Cover up KT case.

It's a faux leather cover, but it looks ok and seems pretty robust.
It's a snug fit and doesn't move about and provides easy access to the power button and home button.
It has a flap that goes over to the back with a sort of magnetic fastener on the back.
It does look like a cheap version of the casecrown but it's quite serviceable.
All in all for the price (I paid £16 including postage) it's good value.
