Hi piano guys, I own a PX560 and yesterday went into a musical instruments shop.
Played 10 minutes on a PX-S1000. Key action is the same for both instruments.
I noticed no difference ... even the piano sound is the same.
I like more my px560 because you always know where you are (settings) ... on a S1000 or S3000 you have no display ...
enjoy music
