That's a smoking deal. I got mine circa 1977, I think for $150? I don't have dwell to check anymore but last I checked (Dad still has points in his '70) it was all still working. I was still a mechanic when I got my set, the dwell failed almost immediately, so I asked our Sun service guy if he could do anything with it. He just laughed and said call ACTRON, it's their stuff with our name on it. So FWIW, my dwell meter is a warranty replacement.
