There are many great show lines and working lines, you also have some breeders who cross these lines as well. Von Lotta is a good breeder located in GA. Their pet puppies are priced $1500-$2000, their show quality puppies are more.
I would look into breeders who have older puppies that hold them back and decide they would do better in other homes as well.
