As something of an update, I've put plenty of hours in with my main digital piano:-
Some months back, I bought a keyboard to use on an X frame stand in my bedroom. Ended up not getting any use out of it - it didn't seem relevant, as it only had 61 keys, and wasn't a piano action. So I was keeping my eyes open for a cheap, slab based digital piano.
Then Casio started selling the PX-150 with the official stand and pedal board at a very decent price, was enough to tip me over the edge, and as a digital piano (in terms of actions, features, controls and abilities) is identical to my main digital piano, even if "packaged" differently, I ended up splurging on one for upstairs.
It's the more contemporary packaging / styling for a digital piano, so minimalist size and foot-print, but still the same 88-key action and width, just quite compact (many use the PX-150 and older brother PX-350 as stage digital pianos), although still with a compact stand (that's actually a smaller foot print than an X-frame stand), and with the 3 pedals.
Looks like this:-
Even at the entry level, digital pianos have become very impressive:-
