Think about it this way.. compare BPs to two other very popular and easy to care for reptiles: corn snakes and leopard geckos.
You can find morphs of both for EXTRAORDINARILY cheap. $25 for an amel corn? Not unheard of.
recessive morphs and double dom/co-dom morphs for BPs will probably bottom out at $100-200, simply because BPs aren't as prolific as corns and leopard geckos. This will take a while, but I think they will eventually get there and maybe even cheaper.
As people always say though, a quality animal can command a much higher price. Think about the extraordinary normal females out there that a breeder wouldn't part with at all, because of how important she is to a specific breeding project.
