I've seen breeders selling BCCs for prices I can afford. I'm not wholly committed to a BCC, but I prefer them to BCIs. If I can't find a BCC within my price range at the show, I'm content to take a BCI or even a Dumeril's.
And yeah, I'm sure they're out there, but I haven't seen any in my searches. All the pro breeders have multi-genes and all the FaunaClassifieds/Kingsnake ads are selling either multi-genes or adults. Maybe I'm just looking in the wrong place.
