not sure about san diego, but i do believe there is a reptile store in oceanside which isn't too far from san diego. i think it is called LLL Reptiles.
Believe it or not, the Animal House on University runs a pretty clean, tight little herp breeding shop. They are super sweet guys. It's right next to a taco stand, the parking is tiny, but you couldn't ask for a better little shop.
They are who I got Drake and Pyra from.
(I used to live in ABnormal Heights. It's pretty Normal there now.)
As for individual breeders, yep there's a few there.
