I bought Make Your Own Patterns by Rene Bergh. I used my 40% off coupon from JoAnn, so the cost was only $10.77. After a preliminary reading, I think I could make a pattern for a simple pullover blouse and skirt. The book gives step by step detailed directions on drafting each line in a bodice front and back, sleeve, pants and skirt. Then, it gives directions for drafting style details like gathers at the neck, shawl collar, kimono sleeves and pleated pants. There is even a chapter on drafting a pattern for jeans. Quarter scale pattern pieces are included with directions on how to grade up the pieces. If I never draft a pattern piece, the information on grading up will be worth at least the $10.77 I spent.
This is the first book on pattern drafting I've read, so I have nothing to compare. This 127 page book isn't intended to be a definitive text on pattern drafting. I still would like a little more information on grading-up. It is a good introduction, though. Now that I've seen this introduction, I can look for the additional resources I need. After I work through a few pieces in this book, I can move up to a more "intense" text.
