I've never read their book, but heard it has excellent info in it. The best thing to do is read,read,read, and absorb as much info as possible. I went to everyone's website and read their breeding info pages. (Markus Jayne has an excellent pictorial) I purchased NERDS book and thought it had geat info in it. I also bought Dr Sewards DVD and found it very insiteful, but nothing beats the experience of raising your animals and understanding their behavior and witnessing it first hand. One things for sure it's very addicting, and at times very frustrating also, but it's worth the frustration. Good Luck! Chris
