Where is DonM when we need him?
After seeing his creativity at work in building the "Redneck Rack" for his PSR 2000 and hearing about his $11 monitoring system, I am sure he can offer a solution that would not cost more than 27 cents.

Seriously, the music stand only fell off during two jobs before I decided not to use it any more. (BTW - same problem with the 740). Now I carry a heavy duty music stand and keep it off to the side of the keyboard in the event of a memory lapse. Total cost: Hmmmmmmm. After hearing Don's solutions, I am too embarassed to say.
