I got a 3-pedal off Ebay for $26. It took some fiddling to understand the interface; shipped direct from Taiwan. No idea the brand; it says "Foot Switch" and it works so far.

I too put the first pedal on a space,

Pedals 2 and 3 are for use in the Conductor.

Pedal 2 "Loop current section" (can't remember the letter)
Pedal 3 "Stop looping"

The kicker is that you have make sure the focus of the cursor isn't in a text box or it will type the space or letters there. I keep it on a check box, and works fine.
