Disklavier

Hi, 

I just joined the group- I am a professional pianist and music teacher, 
considering a disklavier as I shop for a new used instrument. I will be 
looking for used due to my budget and looking at uprights.

Does anyone know where I coudl get info on installing a system into a 
non-disklavier piano? I had tried a few yamaha disklavier's a few years 
bakc and the tone was not rich enough for me, so I am considering 
finding a nice upright that I do like the swound of and looking into 
getting the system installed.

Has anyone done this? If so, did the system work well?

One more thing - if I were to buy one, then decide I did not like the 
piano, how hard woudl it be to sell it and recoup wht I paid? I am 
guessing this is a small niche market?

Any tips on how to look for used disklaviers? I live in the 
Philadelphai PA area.

Many thanks!

Wanda
