Among other things, I liked the keyboard action on the FP90. Then again, the action is a subjective thing.

The weight of the FP90 is a deal breaker for me. You mentioned Casio. I wonder if you considered the 560 by Casio?

Now that I play more VSTs these days, I spent more time at the Fatar booth and tried all their keyboard controllers. Their new Studiologic was awesome. The combination of the controller and the plug-in kept me wanting to play on.
