I bought the CaseCrown Ace Flip Case:

I had something like 30 cases in my wishlist & took forever to decide, but I'm so glad I went with this one. It's much easier to grip the fire in the case than it is naked, but it doesn't add any bulk. The screen isn't blocked at all, which was important to me-- it just grips the frame in 3 places on the top & bottom. When holding it in landscape, the bottom grips are easily released so that you can prop it in the stand, and I like that I have the choice of two viewing angles. No complaints from me!
I got this case as well while I wait for the Oberon I pre-ordered. I actually like the case better than I thought I would. The Fire fits snuggle inside. All four corners are protected. You can charge while in the case. The stand function is easy to use and works well. I like the elastic band that holds the case closed. If you want a basic case that also functions as a stand, this is a good choice. It was also pretty inexpensive-less than $15 when I ordered it. Think it's gone up a couple of dollars now, but still less than $25.
