Ever since I saw a post about using a keyboard with a bunch of the keys ripped off to control Ableton Live (see $10 Ableton Controller) I wanted to make one of them, but put it in a huge box, and use stomp-switches, unfortunately digikey & mouser have insane prices on them (like $5 - $15 each) Today over at CDM they posted about the footswitch pictured here, and It's a lovely beast. 21 keys (one controls the capslock) for a combo of 40 unique functions, woah.

Anywho, as I was flipping through that post somebody meantioned the cost of those switches, and fortunately for us, provided a source to get them at a reasonable price, about a buck each... nice ... You can get directly to the switch in question here: http://www.rapidonline.com/Electronic-Components/Switches/Push-Button-Switches/Foot-switches/79208
I flipped through a couple pages ... and this shop is excellent, I'm thinking they'll get my business for my next major geek-out project.
