I know there has been a lot of discussion on horizontal cases for the 7100, but I'm looking for a couple of great recommendations??

I have the one (from eAccess-estore.com) with the magnetic flap the covers the 7100. It is pretty good. It is secure and the 7100 does fall out. I don't like it because the screen faces outward and I am used to the screen facing my hip. It good (and obviously horizontal).
