Disklavier

I am not a piano player and not at all wealthy....all that being 
said,I have not been able to put the Disklavier out of my head. I 
have to obtain one...

          1. Are there any reliable sources in N.Calif. to look for 
             previously owned Disklaviers?
          2. I would love some advice on what to look for as far as 
             reliability (ie what to watch-out for...)
          3. What type of price range is fair and expected if I do
             find something?

                          Thanks for any help...Jim
