My Opinion: It is a moderate to well-built Chinese distributor.
I bought it on Ebay ($45) while chasing ignition ghosts a few years ago (was not the fix). It works. I have put a lot of miles on it. Assumed I would put the MOPAR dizzy back in if it ever gave me problems. See a lot of Q's on here about them so thought I would share.
I never did like the curve though. Out of the box mine was coming all in by 1650 with 20' of mechanical advance. After this adjustment I still have 20' advance but it comes in 10' by 1500 and 20' at 2100. My setup likes it so far.
