There is one that I like, but I still find it a bit too flimsy as far as the stand option is concerned :

The same design done like a Dodo case (For holding the iPad itself, I don't like the bungees...) would be better...
Actually, I am using an Apple case.
Frankly, a Dodo case, with an Oberon cover and the ability of providing a stand "à la" Apple case would certainly get my money...
