Switchcraft by Elliott J. Bresler Hot

This is the ultimate tome or "bible" of billet work. If you are interested in billets, or plan on doing any work with billets, this is a must have. Even if you are not sure if you would like to do billet work and would like to learn more about it, this is your best resource on the topic, and you can't go wrong with what you get for the price.
For US$19.95, you get 483 pages of material (at the time of this writing) that is constantly growing, if Elliott continues to release new free supplements to this book, as he has been doing for the 3.5 years since its original release.
The only thing is, at 483 pages, it is a lot to consume while in front of the computer, so I suggest printing it out in small chunks and consuming it that way (a work like this deserves to be put in print - and I would definitely get a bound hardcopy version if it ever came out, although I'm sure it would be more expensive).
The material itself is top notch. You get everything you need to know about billets and billet work, and it is all well explained, including real photos.
There sample routines are awesome, practical, and professional. In many cases, all you need to perform them are some billets. You get some great routines and moves from pro mentalists like Banachek and Osterlind as well.
This book will also inspire your creativity, and give you great ideas for your own billet routines. You will really learn that you can achieve almost any effect (and very strong ones at that) when you employ billets.
All in all, a great ebook at a great price. I rated this 4 stars for usefulness, since you need to be willing to use billets for this to be useful for you, but if you don't mind using billets (which can even be post-it notes, or small pieces of paper), this is very very useful! Get it now!
