Beveridge speakers are worth repairing them if you intend to keep them and listen to them. They are wonderful speakers and when propperly set up are unparalleled. The system 3s are more user freindly than the 2s or 2SWs. I don't remeber how many were made, so I can't give you an idea of the supply, demand is low, as not many people know about them.
Happy listening
