Hi,
yes I think its worth the cost, when I look at it I get new ideas. yes they also cover things like. character design, joints, rods, materials, glossary of terms, and a lot of products & Suppliers. they show you tools you can use, drifferent covering you can use etc. I think it was worth it. You can also look at a sample of the book on amazon.com books they show some of the pages and let you look at the intro.
