I was really looking forward to this tome. However, a very limited introduction at best. Considering the price for a softcover, not worth the effort. I really have enjoyed Jim Teeny articles and etc. This effort would have been a lot better as a pocket book. I managed to read this book at one sitting and don't really feel that I learned much of anything new or useful.
