Don't buy a B&J without an extension track! (That Ebay one doesn't have it). You get 15" of draw without one, out of nearly 25" that the bellows is capable of, and you will never find one if you don't get it with the camera! 15" is barely enough for 4x5, not enough for 5x7.
Anyway, the Ansco is a much more ergonomic camera to use. The main advantage of the B&J is more and bigger swings and shifts.
I have one of each, and greatly prefer the Ansco. The swings, etc., though less, are certainly sufficient. On the Ansco, the extension is built in, always there, and slides out the back from the main track body, so you always have it with you.
