My wife, who is a church organist desparately need a pedal for her portable keyboard while the main keyboard was being moved.

Why does Casio not put more effort into a pedal that comes with such a nice keyboard -Privia PX-100?

I have a CTK-491 keyboard, and the pedal works great

Lets me play the keyboard like a real piano.

Normally, I hate playing keyboards, give me a REAL piano any day, but I don't mind playing this keyboard now that I have a sustain pedal.
