Great !
It's curious this fact: I can feel the keybed mechanism while playing a grand piano as the prolongation of my fingers, with a keyboard I can't feel this

I began to study on a 1800 old piano (yes: wiggle) and when I switched to a modern Yamaha C3 I was amazed by his mechanism, action, feeling and playability.
Maybe the market is different in USA and in EU, here I have read that Yamaha Motif and Korg Triton share the same keybed, made by Yamaha. Triton TR88, that I actually own, share the same RH2 (Real Weighted Hammer Action 2) than Triton Extreme 88, that I have had four years ago. To me this keyboards seems quite good but not as good as that of S90ES, that is better than Motif ES8 (yes, I have had all these workstation). Curious that S90ES and Motif share the same keybed. Maybe have different setups. But, again, I have read that some Korg, like P200, use Fatar keybed (TP40GH).
Finally I prefer don't use worstation but real analog synth, sapling instruments and real instruments. For this reason I need a good master keyboard for composing and fun playing Ivory Boesendorfer heh
The only two doubts that I have to purchase Fatar are:
- durability
- light key (reported in some rewiev)
The Roland A80 that I have found is at 1000Km of distance from me and I can only to confide into the honesty of the owner.
(A80 keybed is a little more heavy and hard than Motif, not graded and not hammer but, to me, feels very good. The key go down well balanced and I can feel the hammer-mechanism sensation, that in reality it hasn't)
