I liked the action on my FP30 for the price I paid for it ($500 USD for a gently-used FP30 with triple pedal stand and bench). I've seen folks describe the playing experience a little bit like running through the shallow end of a pool, and it's a fair description. It's among the best actions you'll find for entry-level DPs. Just not as snappy as a well-regulated grand.
I upgraded to the Yamaha CP88 a couple of years ago, and while it's technically heavier (more force required to depress a key), it feels much snappier and less fatiguing to play, and dynamic control is excellent. There's no escapement but you can find similar action with escapement (if you want it) in the Yamaha P515. It's a good practice board for the 6' Kawai I occasionally play on.
I'm not sure what the 2nd-hand market looks like where you are, but that's where I've had the best luck myself. Local sellers are typically much cheaper than buying off Reverb, and I've been able to test-drive the actions before buying.
Roland tends to have the most complete MIDI implementation, but I'd look at any of the following if they're available to you: Numa X GT, Roland FP90(x), Yamaha P515/P525, newer Casio models (haven't tried myself, but hearing good things), and/or the Kawai VPC1/MP11/MP11SE (though you probably know Kawai isn't known for their quality control these days).
