I just ordered this one, $13.20 shipped: http://www.amazon.com/YooMee-Amazon-Android-Leather-Multi-Angle/dp/B007V9O2FC/ref=?ie=UTF8&m=A1ULPX6MZIVYW9
It's for the Kindle and reportedly doesn't cover any ports or controls. source
There are other colors too: Amazon.com At a Glance: YooMee
Now if I hadn't cancelled my first order (just 16 gb N7) to reorder (16 gb + case), I'd be a bit richer.
