I personally have no problem buying from a person vs a kennel, but they still have to meet my requirements for health testing, and conformation/working of the dogs, and the like. Most smaller kennels are run by a single person or family anyway.
I'd not personally pay less than $1500 even for a pet quality pup unless there was a serious physical defect, these giant dogs are expensive to maintain and manage.
WHen you say CKC, do you mean the Continential KC or the Canadian KC. I have no problem with the Canadian KC, but I refuse to buy pups registered soley with the Continential KC. The Cont.KC barely manages as a place of record keeping, there's no conformation shows, your dog becomes a "champion" by being "inspected" by a judge, and its a favorite registry for puppy-millers cause so little checking is done. Mind, AKC registeration doesn't make things ok, but the AKC does actually have rules about whats expected in breeders and will refuse to register pups if it finds a problem (I'll admit they don't look hard for problems).
