I've never owned a Casio myself and maybe
Casio keyboards don't come up to serious (whatever that is) arranger players' expectations. Casio obviously sees a niche market in targetting those folks who just see a lot of buttons and stuff and are eager to buy a keyboard for little Johnny; they're free to spend their hard-earned money where they want. At least it gets little Johnny's hands on a keyboard and, with a bit of luck and perseverance, he could grow up to be a pretty fine musician who can play with the best of them on a top line board. We all had to sit at a keyboard for the first time and, unless Poppa was flush enough to bring home a 2100 or Pa-80, we probably started out on something pretty ordinary and we developed from there.

As a parent, not knowing whether or not that little moptop stuffing his face with Cheerios at the breakfast table was a musical genius, I don't know that I'd want to be shelling out a bundle on something that may just sit in the corner gathering dust after the initial enthusiasm had worn off, so Casio would seem to be a reasonable starting point, and they're good enough for George to sell at his store.

George, how many Casios do you sell? More than a few, I'd bet.
