I just had mine arrive the other day and haven't had any time to do much more than thumb through it. It's a BEAST of a book and STUFFED FULL of ball python eye candy. If you can name a morph combo that's ever been made, it's probably in there. I can't comment on the quality of information or writing style yet, but the pictures are high quality.
The price is as low as they could make it, seriously. Anything less than what it is wouldn't be able to deliver all the morphs, and that's what the book is about. Given its size and the sheer volume of glossy color print, I'm really surprised it doesn't cost more.
