I absolutely think that buying from a breeder that is knowledgeable of the breed is worth the extra cost. Here in the states, there are a lot of what are called "Back yard breeders" that are just out to make a quick buck by breeding and selling puppies at a discounted price. That discounted price sounds great, but often times, the breeders are not breeding to improve the health and temperament of the next generation, but instead treating it as supply and demand. They often over breed females and could care less about any issues once they have your money. Finding a reputable breeder is key if you intend on purchasing from a breeder.
