If you're feeling really extravegant, you can choose a complete system and joypad colour scheme. They do ship to the UK, if you lived in the US you could send them your system.
Maybe it's just me being picky but I've looked on several sites now and I've never found a skin that's preferable to the original. Most seem to be too "busy" or there's some bit of it that doesn't look quite right, or you can't adjust the colours, etc.
Hmm i'm quite interested in the matte black one... Has anyone bought and fitted any of these? Are they easy to fit and does it give a good finish? Would hate to ruin my ps3 in the process!
