Default Mechanical Tach HEI

I'm doing some winter maintenance on my 1972 and my spark plugs and plug wires need replacing. I'm thinking about also converting to a mechanical tach HEI but prices range from ~$130 to ~$250 for a Jegs house brand to ~$500 for a MSD. Does anyone have any experience in the Keen Parts model from Jegs? https://www.jegs.com/i/Keen-Parts/592/220129/10002/-1
How about the Jegs or Summit house brands? Any other suggestions? I'm fine with paying a little extra for higher quality components but not if it's just branding.

I bought this one. Definitely the cheapest one you're likely to find. Build quality seems to be good, I've had a few miles on with no problems. I don't have enough miles to let you know about reliability. But for a cheap part to get the car up and running after being down a while, it works great.

I run the 50 buck non-tach drive units in my boats. Seem to hold up good.

I had a no brand one in my car when I got it. I never had a problem with it. Its in a box in the basement right now as I went back to a stock unit with a breakerless ignition in it so I could run the Chrome shields.

Has anyone had the opportunity to compare the DUI units to a procomp or eBay version? Any significant differences that justify the price difference?

The DUI distributor from Performance Distributor is custom curved to your engine specs therefore you do not have to curve an out of the box generic distributor, that’s what justifies the cost for me.

Convert your tach to electronic. No more needle bounce and you have your choice of distributors.
