Dynasty Reptiles (Chun goes to the Daytona expo but otherwise it is online), Royal Constrictor Design, nerd, VMSHerp (May not have pied), Stewart Reptiles from Deborah who is an active member here. I bought from DR and VMSHerp but based on reviews and learning about these other breeders, I would be happy to buy their animal if I find something I love and I am confident in their ability to produce and sell quality, healthy eating animals. What appeals to me the most from a breeder is their love for the wellbeing of the animal, and the love for this hobby. Money comes secondary. I'm not sure about BHB, I had seen both good and bad reviews from him even though Brian Barzyck is pretty popular in the hobby.

And most of the aforementioned are online.

You can try your local reputable reptile store. The benefit in that is you would be able to handle and check out the snake in person before purchase. Sometimes by holding one, you or your family may realize it is not what they wanted and change their mind before making a 30 year commitment. Or just picking one up at the store can help you build a relationship with that store as you will need to return for weekly feeders (If feeding live, which you most likely will start with).

I got most except my corn snakes and KSB (deceased) from expo. One was purchased at Underground Reptiles store. I consider myself lucky that for the 30 day period the kingsnake was in their possession, it was not sick, had mites or stuck shed. I do not recommend them for animals or feeders. I would be wary of Strictly Reptiles, Backwater Reptiles or any 3rd party vendor who receives numerous imports/exports, questionable quarantine procedure (if any) and any breeder who don't know the hatched date, last feed, last shed or what it ate. And avoid Craigslist and rescues unless you already have experience working with sick reptiles.
