I ordered mine from fleabay from this seller:

Takes a while (2-3 weeks for mine) to get them but they are cheap (3 for $4), easy to install, and don't seem to affect screen sensitivity at all. The fit is about 1mm short of the buttons on the bottom but otherwise an exact fit. They're not matte/antiglare though, it's about the same as the underlying screen was. I think the same seller had some matte versions for sale though.
