It's not "near", depending on where in OK you are, but there are people who drive from Ok City to Tails & Scales in Derby, KS (just south of Wichita). They've got a great reputation, and they are BP breeders themselves. I work with the brother-in-law of one of the owners, who owns half of the breeding collection.

They keep their available list online, but don't have pictures for all of them yet.

(And yes, Wilbanks is in OKC, but I've assumed that the average hobbyist isn't going to get much of his time. I could be wrong, and I'd certainly like a chance to see his collection.)
