I have an iPad 2, and have been using apple cases for years. I reccomended using the film Invisible Sheild by Zagg. You can buy it at practically any electronic store. I would buy it at best buy or at a mall kiosk. If something happens to it there is a warranty on the Sheild. Think it is $30 now, but it's the strongest and most reliable protection out there.
hope I helped
