Going back to the OP, I think Casio still suffers from a 'stigma' it got many years ago when they WERE producing 'toy' pianos/keyboards ... they were inexpensive units, and they sounded it ... As they progressed, they made better and better units but the 'cheap Casio' stigma remained to some degree ... I know a KB player who was playing a Casio that sounded REALLY good ... he put duct tape over the Casio name because he didn't want people to think he was playing a 'toy' ...
