MSD Pro billet opti
IMHO the MSD unit is "built" better but weather that translates into being "better" remains to be seen.
Whatever unit you get use lock tite on the rotor screws.
I think it was an error by the seller who had it buy it now for 400.
but then I saw it a few days later same seller for 499.
Good luck man

This guy is back to a Delco opti after the MSD went bad at low mileage. Hopefully he will see this and tell you himself.

Go with a genuine stock GM Delco opti and a MSD cap and rotor, or a Dynaspark, http://www.dynaspark.net/advantage, whichever way you go loctite, the rotor screws, MSD is either hit or miss, depending on how old a unit you get, older MSD opti have been known to fail, newer ones not so much. but is it, because not enough time has elapsed, or did they fix all of the problems they had, I hope the latter, but only time will tell.
