Go with a midi controller! If you want two expression pedals for any sort of other gear, the Behringer FCB1010 is a pretty good unit. Seems whenever there's no actual signal, Behringer can do a great job. I had one for awhile and sold it off just because it was very large. I should have kept it as I've found the need recently for another midi foot controller. I bought a Rocktron Midi Mate as a replacement. The Rocktron Midi Mate is smaller, sharper looking, nicer display and has better features, but only one input for an off board expression pedal that you'd have to buy separately. Those are both good units on the affordable side of controllers. Of course, you could always just order a regular footswitch from Egnater and spend maybe half of that for just the pedal, but then shipping and perhaps import taxes would start to close the gap making me feel like having more control is worth that extra bit.
Oh, and nice acquisition!
