In my ongoing struggle with what decision to make when purchasing
a piano, I'm considering buying a gently used Yamaha studio upright
and installing a modern electronic player.  Where can you buy the
kits and what has been everyone's impression of them?  Ideally I'd
like to play them off my laptop.  What electronically transcribed
piano rolls are available and what do the data files cost?
