$1200 is actually a bit cheap.It usually takes a year or 2 on waiting list for the reputable Griff breeders and the good ones won't sell to non hunting owners and conduct an interview of prospective owner.
Id make sure he has all health certs on parents and puppies.Are his dogs in NAVHDA?Does the breeder hunt his dogs?
These are a few basic questions Id ask before. purchasing.
