good ignition module?

I buy only Standard Ignition, Blue Streak if available, from my local Car Quest. I don't shop by price because as others have noted, cheap crap is all over. In my past I've been an ASE Master Tech, and worked parts from jobber driver to manager, including dealership parts. This was back when the retail based stores like Auto Zone and the like were coming into my area. I shop the places the garages use, which is mostly Napa or Car Quest. I've also found unless you're careful, the shipping charges will equal out any discount Rock Auto has over my local jobber stores. The retail store parts are lower quality the vast majority of the time. If you play the parts game well, you may find some things (like Moog chassis parts) can be gotten at those places fairly cheaply and it is the same high quality Moog. But, many manufacturers now have a "value line" of almost everything now which is the cheap crap. It's so real parts stores like Napa and Car Quest have something to compete with against the retail places on in terms of cost and quality. If you find a part with a life time warranty, there is a VERY good chance you will need it. The lifetime waranty is the gimick that makes having to change a part 3 times seem like not a big deal. The good part will have something like a year or so warranty. That will cover defective ones which is really the intent of a warranty. Performance parts wil not carry a warranty in most cases because of the assumption of risk.
In terms of the MP - It might fail, but for me, I'm more concerned with the timing fluctuations and timing being pulled out at higher rpm. There is some truth to the old adage "If you have a mopar, you have a ballast in the glove box". The modules had similar reputations, but I never carried one. I do have 2 spares in my parts bins tho...lol.
