I ended up going with
this one, from Poetic.
At $12 bucks, you can't go wrong. The faux leather feels well-made and the case is solid to hold. It looks nice, too, in comparison to some of the other cheap cases out there. Everything fits the way I would expect and it is comfortable to hold in one hand.
Luckily, I use my left hand, because the clasp is in such a position that holding it with your right doesn't really work. The magnet is for the smart cover is too strong (however, they are sending me a replacement free of charge) and the stylus holder on the side obstructs the on/off button and volume.
Still, I'm happy with it, and it'll definitely hold me over for a few months when the good cases start to come out.
