I have the Samsung case as well. I think it provides good protection and it does work great as a standing case as well. Just wish there was a way to secure the cover closed. I picked it up directly from Samsung for $44 so for $20 it's a steal.
NOTE TO ALL don't buy it from the link I had. They mislabeled the item and its really the Official Samsung silicon back cover. I can ship it back for free for a refund but what a pain in the neck as I can't take my TAB out anywhere for fear of scratching it. Just get it from Samsung, which is what I am doing right now.
