Larry Fine does an outstanding job with explaining how to recognize quality in pianos and how to get the trade-off you are looking for. As I read the book, particularly the first edition, it came more obvious which choices for a piano I would like to consider or weed out. It told me many of the aspects of the various piano manufacturers as well as what kind of sales gimmicks to be alert for when I am shopping for anything. Since this book will do all of this explaining, it would definitely be useful to any piano shopper, whether you are looking for one to use or rebuild. It could be also useful for anyone who is studying the economics because it even shows examples of all the different trade-off combinations that a purchaser can run into while shopping for a piano. The Piano Book is also useful because it has information that would be essential to piano owners as well as piano technicians. It tells them everything one needs to know while moving, maintaining, cleaning, or whatever the case may be. Since this is the case, it could help just about anyone involved with the piano decide wisely what they want to do as far as their instruments are concerned. Since Larry Fine gives information on roughly what the piano market is like in his "Piano Book", he helps many purchasers come to a successful conclusion with their piano purchase or maintence, so definitely before you come to a decision about what you want to do about a piano, STOP! Read Larry Fine's book before making an expensive piano decision.
