Does anyone know of a company that offer's a matted back screen film (in the same sense of Powersupport's front anti-glare film)? I have the PS on the front and was looking for one that was identical to it in the back. I don't really like the crystal film they offer in the set. I'm interested in the same type of film as well (static cling installation method, thicker, not like the Invisibleshield, small cutout for camera). I've seen some on ebay but are they any good? I'd rather pay a little more from a reputable company like PS.
