I ordered a Vizo has a detachable keyboard different colors, I chose black leather, the leather actually looks real instead of the fake kind. I should have it in my possession later today then I can tell you how it feels. Hope that helps.
There are probably several good cases for the Galaxy Tab 2. I use a Moko and have been very satisfied. The price was great and the quality is also good. My model swivels and has a holder for a stylus. I bought one for my wife's Galaxy and liked it enough to choose it for myself, as well.
