Hi, I'm from Chandler AZ, and I know what some people call good breeders and what I call a good breeder are two different things. I found my breeder through the YTCA, and had many conversations with her before I decided she was the best breeder for me. Take you time finding someone who knows the her lines well, and guarantees her pups. Here's a link to YTCA referrals.
