WALDORF XTK action on keys?

Are their any users who actually have the Waldorf XTK who think it has lousy action? I was thinking about buying one.

I just recently acquired a used XTk that is in almost new condition. The keyboard is very heavy because the keys are weighted (but not piano-action). I find that the keyboard is very fast and responsive, and the aftertouch is very dynamic and controllable. I can't imagine a better keyboard for a synth. -pc
