I've used Henderson's for bike frames and car wheels, though I've seen all manner of stuff hanging up.
Can't really comment on price - I got charged 60 notes for a steel frame to be blasted and powder coated, don't know if that's good or not.
Quality of work is excellent. The bits that needed to be taped up where etc. etc.
Only real issue I had with them was tardy time keeping - Let down repeatedly on a completion date: Orginally told two weeks, finished up being seven weeks before it was done, and that was only after I started to get irritable and short with them.
So, yes I'd recommend them as long as you weren't in a hurry.
