Try Teri Cuzzetto of Takari's Basenjis. She's in Gresham, Oregon and last I heard still has a R & W boy left from her litters. She's on FB if you want to see photos.
She's a reputable breeder and her lines consist of champion show dogs.
Let her know Helen referred you and good luck!
Also, is this the link some of you used but having problems due to regions and viewing rights?
If you can view, catch the "not that trainable" B. at 26:16. With that face, he needs not be at all
