There is only one manufacturer of the DISA valve, I'm told.
Personally, I think that manufacturer should be shot - but supply and demand being what it is - you don't pay what YOU think it's worth - you have to pay what everyone else thinks it's worth.
If mine goes south, I'm rebuilding it. I don't like rewarding the original manufacturer for making a lousy design (think pin ingestion).
Please read the suggested threads, where the best always add value to those threads, either by pictures or by descriptions, so the next person with the same problem stands on your shoulders.
