I did a Power Master unit on the old van (RIP) and would do it again if I was in the market for another one.

Idle output is better, it is not a Denso by any means but still vastly superior to the mystery junk in a box at the parts store.

Reliability as well was never an issue.

The rebuilders keep taking the same old worn out crap and just keep reusing it over and over again. keep cutting down the slip rings until there is nothing left. Mixing and not keeping the OEM matched stator and rotor together so the output is all over the place ect.
