I got the belkin folio case.... it make the zune kinda bulky, but I don't mind, it hangs off of my belt loop, and has a sexy micro fiber interior and leather exterior. Some times the microfiber lint gets between the screen and the screen protector, but I just whipe it off, and it doesn't come back for a few days... sometimes more..., but over all It's a great product.

pros:
It serves as a stand so I don't have to hold it. I can set it on my lap, or my desk
hookes up to my pants (my pockets get tight when i'm on my bike)
doesn't slid around when I drive (becaues the microfiber sticks to my dash)
It's sexy (yellow and black, some people don't like it, but I do)
it's got a tri fold design and covers the completely
Hard to steal when on my pants

Cons:
lint from the micofiber inbetween screen and protector.
the middle button ring and button are inset (a little hard to get used to)
the play and back button can be pressed accidentally.

I've never used any other zune cases, but I've seen them, and I don't really like them. people get their mp3 players stolen because the use a pant clip, and people can just walk up take it and run. They can't to that with mine because I use the wrist band to loop around onto my belt loop.
