A friend has 6 LMI truss mount dimmer bars. They are 10' x 1' x 3" approx size, have 18 1k circuits per bar, speak DMX, and take 3 phase power. Most dimmers work, theres a few dead ones. They're free to a good home, but have to be picked up in Long Beach (we can't move them as they do not fit in my friends pickup or my suv).
If you are interested, PM me.
