I have a flip cover which kept breaking on the plastic so is held together with a paperclip and hot glue. nice case but not robust enough for me.
I also picked up a fintie which is a nice tight perfect fit if a little too closed around the screen for full screen use. had to come via ebay US but cheap enough and utilises the cover off feature and a similar folding stand. from what I've seen its the best out there. I'd also like a ballistics for it but for rough stuff I'll take my playbooks.
my next course of action will be to hack a wireless charger into one to counter a broken usb port.
