Nevermind, doesnt have to be Ebony material like i said before, just to have Heavy Weight...
But i looked to Casiotones CT S1, not sure if its 61 keys tho, but looks like it.
Anyway, there was that nice PX-S3000 with everything, slimmer but 88 keys...i think its even better than the 560 to me. But Price being 700-800$ is quite excessive, tho
But i looked, it has the DarkMode (NightMode) LCD Touch Screen, the type of visual that would fit for me....
However, as im owning ctx-5000, from start wasntempted with semi-weighted keys, coz didnt want to be "too heavy" ; started using Normal mode, then switched to Heavy, its better, but wanted slightly Harder, tho) and disnt want "too long" with 88 keys tho
Nevertheless, as u said, there arent any 61 keys that offers heavy hammer. Oh dear
