Comon Cliff,
I started many years ago playing an organ, so I am not a pianist (hope I spelled that correctly). I have a friend who bought a second hand piano he got by trading his carpentry service. It's an old instrument, but it blows away a Yamaha PSR540, PSR550, PSR2000, EM55 away. Never tried a PSR9000,S90, or a motif. It would take 65 megs of wave ROM, for the piano sample alone, to sound anything like a real piano. A setup like Frank Rosenthall has, might do justice, but he has gigabytes of wave ROM on his computer. PSR2000 has 16 megs split on 800 different sounds.
