I think selective breeding goes hand in hand with quality animals and good reputations.

I have certain snakes in my collection that are only for certain projects.

Last year I produced some pastels that were not up to my standards so I sold them all and the dad that produced them. I dont keep a huge collection so to me if it is not a great example it doesnt stay here or get bred.

When people post how low a price they found my thoughts are "I wouldnt want that dog in my collection just because he's cheap"
Been there done that.

Nice animals will always be priced higher, as most things you get what you pay for and you are also paying(hopefully) for integrity.
Respectable breeders will give you honest and correct info of the animal you are inquiring. Selective breeding is part of what you should be looking for
