If you like the clean, uncluttered look of the K2, but still want protection, the Invisible Sheild may be exactly what you're looking for. They just notified me that they have the Shield for the K2 available.
These are more than just a "skin", giving true protection for your precious Kindle. I've used them on my cell phone and PDA, and absolutely love them.
The kit includes a screen protector as well, though I'm not sure I'll use that piece, as it might add a bit of glare.
You can find the Shield for the K2 at:
