Nick Waples, Neil Roper, Karl Norris
I do remember Euan saying that more work was required to his cnc head to get the gains they wanted, at £1250 or whatever they charge I don't know if you would be better just to get someone to do all the work by hand.
All 3 mentioned above have been getting fantastic results for a long time, out of the 3 I would use Nick as I have used him for years, however he is probably the hardest to get hold of these days.
