I cannot imagine a single copyist who would have the income to drop over $700 on a book like this, which is what’s asked on Amazon. And yet if you work by hand for a living, then it’s the best book that I’ve ever read on the subject. Clean, clear, concise, and precise. If you see a copy at a yard sale, snag it! But Google around for some other guides – Berklee has a couple, I think.
