I recently broke the bank and went ahead and picked up the Galaxy Tab 10 Keyboard case by Samsung and its awesome...maybe not too protective but awesome.
Hi! I had also bought some Samsung Galaxy S3 / S III Cases and Screen Protectors from the store called SF Planet where i got good Quality Cases, Screen Protectors, Car Chargers, Wall Chargers and USB Charging Kits. I had Bought all my accessories from there at low price. Try it by yours!
I am using the Protecting Leather Case With Stand... just $9.59. you get over that it works just fine.
I used 360 Degree Rotating before,but nondurable.
