A lot of students from the UK at our university used RPWORLD in china to get stuff done. The turnaround is incredible i had bits made and shipped out to me in 4 days.
I would say though that from a UK perspective the SLA is not any cheaper for us because they have to buy the resins from Europe. CNCing however was dirt cheap.

They do offer to do the finishing for you as well and what i saw the finishes were pretty good, however personally I prefer to do that sort of thing myself.
