Finally found a sufficient Case.
I have gone through three different cases of the Zune. One being a cloth based one where the plastic screen would constantly get dirty and the window wasn't square blocking off sections of the screen at times. The same applied for another cloth based case I owned. The third case was the Belkin hard case that didn't protect my zune at all. All three ran from $20-30.

Then I found this one and decided to give it a try, my Zune 80's case was stuck in the cloth pouch that is given with the device and I constantly worry about how unsecure it was. This package here finally fulfilled my requirements: (1) Provide access to the Sync cable while in the case. (2) Provide access to all buttons comfortably. (3) Protect the screen without obscuring the view. (4) Have some kind of screen/protection over the Zune display. All four were met with this package and I am very happy with the optional material: The Arm Band & Kickstand.

My only two negative comments to this package are (1) the kickstand and Belt clip seem kind of cheap to me. I don't plan on using them anyways so that's not an issue for me and both are easily removable from the case. (2) I would have preferred something better than a screen protector. Typically I can never apply these correctly, however this time it actually functioned well for me but that is dependent upon the user. Also, any other type of screen protection wouldn't have worked with the flexible material to wrap around the Zune.

For the price, and what this kit provides (My 3 requirements) I have to say this is the best money I've spent on a Zune case. I would have given it a 4 due to the cheap kickstand and belt-clip, however by reaching my three requirements, providing me an arm-band, and being the cheapest protective gear I have ever had while still having my Zune look stylish, I am giving it five stars.

Not very strong and Zune may come out
Back of case got damaged on the first couple of days of use. Top easily gets off the Zune and it may come out

Excellent Quality
Ordered this product on a Thurday night and have it in hand Monday afternoon! The quality is excellent as noted in above reviews. The only change I'd make it would be to provide some directions on how to install the belt clip. I had to work on that one a while until I realized that the circular attachment not only releases from the clip but also the center section unscrews revealing a threaded section that slips through the small hole on the cover. The attachment then can be reconnected to the clip along with the cover. Very clever arrangement.

Great Case
Purchased the Black Silicon Skin for Zune 30GB. I have three cases for my Zune, and this one is by far the best. Easy to put on/remove and has a very snug and accurate fit. Stand is remove able but is nice to have when watching movies. Sturdy material makes for good protection, and the added screen protector is a nice bonus. Buy this one, can't beat the price and most likely, you won't find it in stores.
