An item like this is for people looking to do a total restoration, and not folks just wanting to slap the cheapest solution on their machine.
This seems like a premium product… so I wouldn’t try to compete with 3M generic.
A month or two back, I reached out to tomytronics and may have purchased the last one he had on hand.
I was warned that the design needs shielding because it is highly susceptible to interference. Got my connectors ordered, and now just need to find time to solder it together.
