I use an old USS (Ultimate Support System)
"A-Frame" stand, works great. IT's nice and
wide, so my 18-note MIDI pedal board fits under it nicely. I attached the music desk from a music stand, right to one of the upper supports, so it'll hold a big heavy music book easily too. And I attached wiring, lights etc. along the tubing, so that at a gig alot of wires are "pre-run" for me.

Don't know if they still make/sell the A-frame style or not though . . .
