I think the best advice on the topic of price is the advice given at the BCOA Questions for Screening Breeders.
"How much do you charge for a puppy?
Basenji breeders in the U.S. charge between $800 and $1000 for a companion puppy on a spay/neuter contract. There can be legitimate reasons for charging more or less. However, a breeder who is selling companion puppies for significantly more or less in your geographic area should have good reasons for doing so. A breeder whose fee is significantly below market rate may be producing too many litters and needs to sell quickly. A breeder who sells at an inflated price may be seeking to line his/her pocketbook at your expense."
I would add to this only, "Know what you are paying for". What you get for the same price may be significantly different. One breeder may have invested significantly more money in their puppies than another asking the same price. Verify health testing using the OFA website, ask what the breeder sends home with their puppies, visit with the breeder and meet their dogs. Even better visit with several breeders and see lots of dogs.
