Simon sent me this news:

www.psptree.co.uk are offering a new bolt-on to the existing PSP screen replacement service. They are also providing a faceplate fitting service where you can choose from 10 faceplate colours and they will fit it at the same time as doing the screen replacement. New faceplates are available for 14.99 including VAT and labour. Faceplates are also available for sale separately. Also for sale are sets of different coloured buttons, and spare battery covers.
