player systems - pianodisc and more

[justharmony]

Sorry for the kinda-sorta double post... but I wanted to get feedback on player systems in general, and pianodisc in particular.  The challenge is finding a decent second-hand piano with player/recorder system for under 10K.  Remotely realistic/possible?  Time is not an issue, so that might help (i.e., if it takes a year or longer to find the right thing, that is fine).

General comments, recommendations, opinions welcome.  Any commentary on upgrading old pianodisc systems most welcome, also.  Lay it on me!

Thanks so much.
