I've been using these chaps on/off since 2003, they are local to me and I can definitely recommend them for any work you need doing.
They've just fitted new discs, pads, lines, clutch line, break and clutch fluid, and oil change - so I'm off to get some heat cycles into the new discs
EDIT:
I've decided to use other recommended places now (Kaizer/Abbey/TGM).
Some of the work was good, some of it wasn't (ex: crushed brake pipe).
A couple of guys that work there are very competent though.
