How good is an I BACH piano?

[donsveertje]

Hi,  I have a piano from the brand I BACH and my pianotuner loves the piano a lot, just like myself. He even wants to buy him for more than 10.000 Euro. All I know of the piano is that he plays very good, has a goed sound (full) and it has a "Renner" mechanics inside. Before I bought him, he was used as a concertpiano.
But nobody is talking about this brand in this forum, so I'm curious to the thoughts about piano from this brand I BACH
(sorry for my bad English).

I never played one, but would like to, some day.

I have one and it has perfect  sound.The only disadvantage is that you must concentrate a little harder with your move (fingers) and every note because has a somekind  limitation with unnecessary moves (if you have very long fingers?!).The benefit is a bless because you play perfect and with outstanding technique(if you are a professional) in other pianos like steinway or Yamaha as well!!
