Kawai is the answer...
Mp7 or mp11..

Best keybed in the buiseness
Great sounds to
And very very versatile as a master controller for Ketron..

The MP11 has less sounds, but even better touch it weighs a ton tough
The MP7 has still good touch, much better then kawai, and has a full set of sounds..
Weighs i think half of the mp11.. even has a virtual drawbar organ and keybed seting onboard..
