I'm not a big fan of the hard shell PSP cases—too much work to remove and replace after every crowded subway ride. So I like these garish custom-colored PSP faceplates from E-linksoft. The faceplate package includes button covers and a lens to protect that screen from scratches. Comes in Ferrari Red, Chrysalis Blue, Liquid Silver, and Xipod White (can you believe they're naming colors after the iPod already? Jeez...). Sounds like some work is required to attach the thing. Get one on pre-sale now for $50.
