KP,
I'm glad to hear that you are making progress with your search for the right digital piano for your family. Out of the three models you are looking at, (P155, YDP140 & 160), I would still choose the P155 because first and foremost the piano voice quality is much better than those and that's one of the most important features. Secondly, it has 128 notes of polyphony compared to the YDP's 64 notes (polyphony is important as it is the maximum number of sounds the keyboard can sustain simultaneously). Thirdly, the P155 has more voice presets 17 over 10 in the YDP 160 and 6 in the YDP 140.
I think the only benefits that the YDP 140 and 160 have over the P155 is the piano cabinetry and the YDP 160 has 2-20W built-in amps versus the P155's 2-12W amps but you could always connect an external amp/speaker system into the P155's AUX OUT jacks if its built-in speakers aren't enough for you.
Just remember to try these instruments before buying one--it's a personal thing like trying on a pair of shoes.
