I was loyal to Technics , from the kn1000 to the Kn7000. Some were bought unseen. I had problems with the Kn6000, after three trips to repair they sent me a new Kn6500.

No problems with the Korg and Yamaha keyboards I have owned.
One problem in all the years I am playing, that says a lot for the Technics, Korg, and Yamaha.
