One of my boys is from Jan Kahl of Jadaka Basenjis and she is located in MO. She is a responsible breeder and does all necessary health testing. She's also a very nice and helpful person! I'm very happy with my Morgan.
Most basenjis have been placed this year (most are born Oct-Jan with the odd summer litter here and there) so it would be a good idea to get on some waiting lists for this coming season. Like Pat said, do your research and check out the breeder before you decide. If they are hiding something, move along.
