I agree with Mr. Boyes. Having borrowed a copy of this book, I count myself fortunate I didn't pay for it. It is a basic tutorial for novices, without a clue on "where do we go from here?". The technical information appears to be a regurgitation of machanics availble from many other sources. Nothing new here...a basic anthology of known methods. I seriously wonder how many of these reviews were written by the author himself?
