Disklavier

I went to the Yamaha web site and found the page for the DGH1BII.  It 
is called a playback only player piano, but in the fine print, it does 
sound like it can do some kind of recording of live performances.

Is it possible to record someone that is playing live on the piano for 
later playback?  Sorry if it's such a newbie question but I've been 
searching all over for an answer to this and I'm still not certain.

Also, I'm looking to buy this piano.  What is a fair price to pay for 
one that is in good condition (requires no work and is well 
maintained)?  Would you avoid such an old disklavier and instead look 
for a newer one?  I really don't know how much better the new ones are 
but they seem to have more bells and whistles.  I'm mostly interested 
in having a player piano for entertaining and also one that I can learn 
to play on and record my sessions for playback.  A good sounding piano 
wouldn't hurt either, but I've been told the baby grands don't sound 
all that great.

Thank you.
