I can't find anything on puppiesflux.com or puppieflux.com, and that concerns me. Short answer is... I just don't know.
That said, there are plenty of awesome good breeders here in California. I'm not sure what you might consider a good price, but most breeders aren't in it for the money. They're lucky if the break even, but rarely do from what I've learned. It costs a good amount to build a kennel and get all the equipment, heath test your dogs, pay for vet visits, hip x-rays, register with OFA, AKC nd BCOA, feed them and vitamin them, vaccinate them, and the list just goes on and on and on.
Every legitimate breeder I have ever spoken to insisted on a phone call and/or a personal visit. They interrogated me for a good amount of time too. The tested my knowledge of not just Basenjis, but dogs in general, wanted to know about my home, yard and fence situation, who were the people in my home that would be interacting with the dog on a daily basis and what were their ages, who would be home with the dog the most, how often would we leave it alone, etc. The breeders wanted to know all of that before they'd even get to cost. They seemed less concerned about cost and more concerned about the home they might be sending one of their puppies to.
Here's a good article from BCOA on Screening Breeders. I really recommend reading it a few times.
Here's a BCOA Breeder Directory of California Breeders. Some have retired, some are active on this site but may not be breeding as often anymore, and others you can contact and screen on our own.
You probably know, but in case not... Basenjis come is a range of color combos... Chestnut, Black & White, Tris, Brindles and variations of those (e.g. Brindle Tri or Brindle Chestnut). Many breeders seem to specialize in one or two. Keep that in mind when choosing one.
Basenjis can live to be 14 to 17 years old. I've heard of one that lived to 20. So, you're going to have this pup for a looooong time. Take some time, do you're research, create a relationship with your breeder. Short cutting things like heath testing (e.g. Fanconi and PRA) can lead to devastating heartbreak. You might be able to buy what looks like a purebred Basenji on the cheap, but if Fanconi rears it's ugly head down the road... your vet and medication costs will cost you far more than a Basenji from a reputable breeder.
Hope that doesn't sound to lecturey. I love seeing people interested in Basenjis. Welcome to the forum and please... ask any questions you have!
