Hi Bernie,
It was not my intention to be in any way disrespectul to you as you must know for sure. I was merely referring to the fact that having many guitars, keyboards or whatever you have to make choices and, in my instance, I ended up with playing two out of six guitars. You seem to be using all of your keyboards to your heart's content, that much the better. As long as they give you joy and creativeness that is all that matters.
It is remarkable to notice that owning the boards that you do the SX900 is turning out to be your favourite for the moment.
But then again, it is all a matter of taste. As mentioned so often here there are no poor keyboards anymore. they all shine in their own ways and serve different ears and audiences.
regards
John
