Not sure whether I came across it here or elsewhere. Anyhow I thought that the piano sound, at least in the demo, was not bad at all and considering all the other extras and the very low price I have ordered one on trial. Expected delivery in about four weeks time. There are three demos from the Messe. They are in Italian but if you move on to approx 3.20 minutes the music starts. Specifications can also easily be found, see second link.Wonder what your thoughts are on this little contraption....
