IMO the most concise guidance I've seen is from Zande Basenjis: http://www.zandebasenjis.com/inform.htm It's all good but perhaps too short for people to give it the attention it merits. Runs counter to the idea that why use one page when fifty will do.
I think there is also a note about why you might want to get one. LOL
My first piece of advice would be to know you don't want to let them off the leash. It's a mistake everyone makes but it's one you don't want to make (I confess being stupid and doing it twice with our first Basenji). My second piece of advice would be to not get one too early if you're getting a puppy. They need time to socialize. My third piece of advice would be that the price of the dog doesn't matter. Hopefully you'll have many years together, and by the end the price paid will be a rounding error with all the expenses.
Good luck. Basenjis can be great dogs.
