I certainly think it is worth it, assuming it is in suitable condition, to the person that wants good bread and butter sounds. It was a great big band board, e.g. I had the KN5000 and KN7000 snd still miss my KN7000 sometimes, but time marches on. There are still some that play out with it right now.
