Query: don't waste your time

As an experienced technical theater engineer, I have never used most of the methodes in this book. Warren seems to be too attached to the old "wire frame and paper mache" techniques and hardly ever uses anything else for three dimentional props. Furthermore, there are hardly any common props featured in this book and most of the ones that are featured can be cheaper bought than constructed. There arn't many otherbooks like this out there but any of them would be more helpful.
