P.S. never by things from DecalGirl.com. thatswere i got my face plate and buttons that go here today and they suck.
DecalGirl is a very reliable site and they only resell official products. For example, if you ordered a Camy faceplate, it's a faceplate straight from Camy Pro Gear except it's at the DecalGirl warehouse being sold by them.
They aren't fake aftermarket items, they're legit official items.
Man why'd you rip apart your psp even when you didn't have the clear case? You shouldn't leave internals of electronics lying out of its case too long. I opened up an ipod I was intending to repair the screen of even though I didn't even have the replacement screen yet. When I finally got my parts, the ipod didn't work anymore...
As long as you take care of your parts you're fine...
