I check http://www.faunaclassifieds.com/ and http://market.kingsnake.com/ religiously, aside from those classified sites, you can check the BOI on fauna for feedback on individual breeders. Reptile stores are going to be high priced, but you can see them in person, be wary though because not all stores are created equal. Lots of subpar keeping and husbandry in most pet stores. My person fav is expo's, as you can see them in person, chat with the breeder, and have a wide selection of different morphs / prices to choose from all in one place.
