Hi: The best bet for neon transformers is to nose around sign shops which specialize in neon signs. The junk bin will occasionally reward you. I got lucky by running an ad in the local paper under "WANTED" used oil furnace ignition transformers or neons. The ad ran for a week; I heard nothing for a month then got a call from a local motel. Result: 14 good 15 KV 30 mil trannies!!! Gotta run it up the flagpole and see who salutes. Stephen.
