Thanks all, for the tips and comments............lots of good ideas for my project in the summer.
Gosh, UnkyUB, some outlay for what in current terms was a modest machine. Costs have certainly fallen since then.
My original question arose as the man who did my rebuild is newly arrived in the area, and as such had no local "reputation" to be judged by, and whilst I could not fault his workmanship, I was just curious as to his costs. From what has been said above, his costs are ok, and that gives me the confidence to return to him if problems arise in the future.
Thanks again, one and all.
