I know Betty, and know she has upcoming litters. As far as price goes - you really shouldn't pick a breeder based on who sells the cheapest puppies. Pricing really goes by the overall qualty (genetics/testing/etc.) of the dog - and you get what you pay for, so please ask a lot of questions. Good luck!
