I've been looking around trying to find an inexpensive back screen protector for my iPad but haven't been able to find one yet. I originally had an iCarbons carbon fiber one but really messed up the installation and didn't like the fact that the Apple logo was exposed. I've been trying to find a clear one instead that doesn't cost $20-$30 just for the back protector. Don't care if it's off eBay or whatever but just needed something inexpensive, clear (matte is ok too) and covers as much of the back of the iPad as possible. Any suggestions?
