The Kawai CN22 has been discontinued (May 2010). Check out the new CN23
We purchased a Kawai CN22 for use in our home. We were looking for a smaller digital piano to replace our rather old upright one. This instrument now takes up less space and never needs tuned. Our current piano was at a stage where after a few months it sounded as out of tune as it did before the tuner had done their work on it.
It will do all we need it to do. None of us are great pianists. However, now we can now play our flutes with the new piano, something we could not do with the old one.
