Default Time for a new Opti. Any Suggestions?

It's that time again... seems like 70,000 miles was just 5 years ago. It's been a while since I had to do this and was wondering if a GM unit was still the way to go(so expensive). I have a 1993 model. Has anyone had any experience with Summit Racing PN SUM-850059 ? (its cheap.) I'm going more for a daily driver than a race car, but what about the MSD units? I've heard varying reviews about them. Any one have any suggestions?

1. GM or Delphi
2. MSD

Nothing positive for
Accel
Cardone
E-bay junk

Chandler Motorsports has some positive feedback on the net.

I hope MSD has addressed their issues by now. Have not been exactly trouble free for many of my customers.

MSD's are pretty damn good now a days. The older ones were trash, no doubt.

MSD cap and rotor kit on existing base.
treat it like a tuneup on older engines, just a cap and rotor.

I wouldn't put the MSD base on if I got it free.

https://www.rockauto.com/catalog/mor...361&cc=1035908

433 bucks.

http://www.summitracing.com/parts/ac...FdGd4Aod6lIA-g

445 bucks.

http://www.sears.com/shc/s/p_10153_1...0125xMPALLx028

480 bucks from Sears? O.o ROFL.

By the way that was really hard. Typed in Google AC Delco Optispark.

I bought my car with a MSD changed like 8k before I got it, test drove it 3 times. Bought the car, 2nd day home the Optispark took a crap. Tried a Chandler Motorsports, didn't work. Put in a Ac Delco been fine for years now.

I should find Chandler and throw the Optispark through his window.

Delphi should be the same thing as an AC Delco.

This is the set up I ran for years. Zero issues. New owner put a complete MSD opti unit it at end of last year. We'll see how it runs this year. I think he made a mistake.

If you're stock AC Delco/Delphi.

If you're modded and spinning anywhere near 7000 rpm MSD.
