I thought it was great! It's really neat to compare the design and techniques among bowyers. Yeah, the original information was from 20+ years ago, but the techniques are still pretty much the same today. I suppose if you had the original the new edition would be a bit of a let down, but if you don't have the original, it's all new. There is a section at the end that's basically a "Where are they now" section.
Bottom line - well worth the price. Don't hesitate to buy it.
