Hello Bernie
I have owned a lot of Technics the last one being the Kn7000. Bought the 7000 when they came out and have not had any problems. As Audrey said the keys and buttons show wear but it is still going. I also purchased a Korg Pa3x. It is a really nice keyboard but as Bill N, said it is very hard to get into it and make it do different things. I would never get rid og the Kn7000. The Kn7000 sequencer with the APC and Control function was way ahead of its time. Roger B.
