If Divineo's chrome PSP faceplate wasn't your bag, the Talismoon Evolve series might be.
According to Divineo, everything needed to create a new-look PSP is included in a single package, consisting of the faceplate color of your choice, an illustrated diagram, hardened steel jeweler's screwdriver, a dazzling set of diamond series buttons as well as a finely made polishing cloth to preserve the appearance of your PSP for years to come.
If you want a custom look for your PSP but can't afford one of Sony's Signature PSPs, this may be an excellent way to go. And for only $15, you won't be out too much if you don't end up liking it. However, keep in mind that removing your face plate will void your PSP's warranty.
