The FS200 is a MIDI foot controller made by Roland a few years back. The product is discontinued but are worth grabbing if you see one. Will send program changes and MIDI controllers, and includes one pedal. The pedal is light but durable and, though the buttons are plastic, they are solid, but more importantly, they are quiet. Metal mechanical switches can be very noisy in acoustic situations.

Bob Sellon - I picked up one of these a few years ago and it's been working great.
