Marcel is right...Yamaha is just not for everyone. I had an Electrone organ, which I liked and have a Clavinova CPV 65...great piano.
But, I bought a PSR 3K and just didn't like it. In fact, I haven't really been impressed with any Yamaha arranger.
I like Ketron products and will continue to use them until I find something better.
In the meantime, the 3K is in the den.
Just my opinion....hope everyone is happy, with whatever you decide to play.
