LOL. You will go through those screen protectors. Getting one on the Vita is difficult as Hell. Just giving you a heads up. I eventually got a screen protector on my Vita 1000 finally after 10 tries. I just couldn't have any scratches on that OLED screen. I feel like it was worth it.
I got a tempered glass screen protector for my Vita 2000, and it went on perfectly the first time. Always remember to do a test run of how you are going to place the screen saver before removing the backing on the adhesive side. Also, I have had success placing screen protectors on my devices in the bathroom right after I take a shower - the high humidity pulls dust out of the air helping to minimize dust contamination between the screen, and screen protector.
