Another reason I like Don and Kathy, is that they have written beginner cornsnake books:

http://www.amazon.com/Soderberg-Captivity-Professional-Breeders-Paperback/dp/B00RWRCWLY
They have been breeding cornsnakes since Dinosaurs roamed the earth. Every forum post I could find on neutral places like reddit/cornsnakes.com/elsewhere are generally positive on Don. I started emailing him before my purchase with walls of text and he wrecked all of my questions thoroughly and then some (he schooled me good!).
