Absolutely brilliant. Bought a really old Diamond off of e bay. The poor old girl has some problems, BUT, Doug at Diamond has been in touch with me and has provided some great detailed advice to try and sort out any problems, and is more than happy to go further to help me upgrade her. This is a man with great pride in his workmanship (not many left now). Just wanted to share this with other scroll/fret saw enthusiasts. All the best
