$13 is kind of steep. Seriously, everyone, do yourself a favor and goto EBgames. The Hori PSP screen protectors are the best on the market and go for $5. All you've got to do is cut about 2 cm off the end and your set.

What is funny is that site is selling Gameboy micro screen protectors. One of the nice features of the micro is that the faceplate doubles as a protector. Once it gets too scratched up simply toss it and get a new one. Those are $5 too.
