Last I heard, the Breed Club secretaries had more people waiting or wanting pups than were available . You could get on a list for a Basenji next winter but I very much doubt you will find one still unsold. Go to the website of the BCGB, or the Northern Basenji Society as you are in the North and you will find email addresses of the secretaries. They will put you in touch with breeders who may be planning a litter for puppies to become ready to leave the nest in about a year's time.
Its a long wait I know, but you have most probably missed the boat for now.
You are welcome to post me privately.
