Not all "family breeders" are backyard breeders after your money BUT they have most likely only bred their two dogs for "the experience" rather than bettering the breed.
If you want to check if they are serious about breeding, ask them what all the blood tests showed regarding possible health issues later. If they can't show you the results, best look the other way.
I'd stick with Mitte who has been part of this site for quite a while. He will point you in the right direction.
