If you need to swap out the suspension fork and don't want to spend much, just got a nice 20" RST fork for one for my R20s which seems just as cheap and cheerful as the one on my DT) from AEBike in the States for very little cash.
I've seen a few DT IXFSs around London recently - all off them black. They are certainly striking looking bikes, though I prefer them in white. Makes me feel a bit guilty about leaving my (white) IXFS in the garage in favour of my Mezzo.
