Hi Godwald
Your tastes run like mine. I'll bet you would love the Technics KN6500. But this is a very expensive keyboard. Even the KN5000 would please you. However, the Yamaha's and the Korg's will also satisfy you as well. And, the best deal for the best price would probably be a Yamaha 740 or 2000!
But, as we have said around here many times in the past - go out and try them, play them to see what ones you like the most.
