Knowing how useful a paper manual can be when working with a new piece of equipment, over the last 12 years I have purchased a few, for myself, my wife and sister-in-law. I always purchase the wire-bound edition as it is much easier to use on a flat sirface and when the pages are turned back on themselves, making for a completely flat book. The manuals are, in effect, just a bigger version of the manufacturer's manual but of course, they are seemingly no longer supplied. I can thoroughly recommend them from OTC. The manuals are printed on good quality paper with a very strong wire binding. The service has always been excellent with speedy dispatch and good packaging.
