Best sony psp faceplates, protectors & skins according to redditors

Here ya go! I think you are referring to the PSP 1000 as the camouflage version. If not just search for your model under the amazon search bar.

A wet application screen protector such as this may work better at hiding scratches than the standard static cling ones. I personally have that one and put it on a vita that was scratched to hell and it hid all of them but the really deep scratches.

It was supposed to be white, but came looking like a condom!

The grip helps a little. It’s mostly for comfort and protection(no pun intended) in case I drop the controller.

Wish list thingy

I can't speak to the quality of replacement parts, you might get hold of a faulty psp and use it as a donor or else try ebay or these:

This uk supplier has a pricey oem part.

Amazon uk have a 3rd party supplier of non-original parts with an odd choice of 2 prices.
