This year he has done a headgasket change; cambelt change; timing and idling sensor repair, all above satisfactory to the point I would not consider taking my MR2 anywhere else for mechanical work.
Most recently, my gearbox broke and he replaced it with a nice rev2 LSD box
(see my related topic) very quickly and I'd like to thank him, Jay and Anthony for all their much appreciated work over the last couple of years. 
I unreservedly recommend SBiTS to anyone with MR2 troubles living in the North of England.
I believe my car to be one of the best mechanically sound Rev1 turbos in the UK.
Cheers guys!
