Case for Nexus 7 2013? Treegloo, Dodocase, or Smart cover?

By some miracle I won a new Nexus 7 in a raffle and I wanted to know more about some of the case options.

How is the Treegloo case? I've heard some good things but also horror stories.

What about the Dodocase? The classic seems expensive but I'm not sure I trust the adhesive ones.

And is there anything like the iPad smart covers that are thin and light, double as stands, and isn't too expensive?
