DUI vrs. Ebay HEI distributors
Has anyone tried the HEI's that you see on Ebay for $69. ? I know the $300. will be a better unit but come on it's $230. to use somewhere else.

I am running a DUI. I bought one when they were almost $400. I also have the 10mm Live wires. Sure it is expensive but I have been very happy with mine.

I have not heard from a direct source but there is talk on jeeps and other applications that use the HEI setups (5.0, etc.) that some of the cheaper ones have caused harm to the cam shaft or even broke the shaft on the dizzy. Don't know the validity either.

Not sure that helps ya.

I have an e-bay HEI and i have had zero problems. the only thing i did was run a 12 volt wire from the battery to the HEI due to the factory 12 volt hot for the coil has a resistor and will not give a constant 12 volts that the HEI needs.

Thanks, I'm still on the fence, but it's tempting to try the cheapie

Sounds like your mind is made up and its been a few weeks since the last post, but I just want to offer another perspective. If your engine is old enough to have left the factory with a points type distributor, I would think twice about replacing it with an HEI.
The HEI will give a hotter spark, with less maint. A big bonus for sure. But what you are giving up is simplicity and the ability to troubleshoot on the trail. With a points ignition you carry a set of points, a condenser and maybe a rotor and cap. You can set them with a matchbook and get back to camp or the trailhead.
With HEI if it craps out on the trail the only thing you can do is throw parts at it and hope one of the parts is not defective out of the box. Rare, but it can and will happen.
Plus the expense of spare parts. I have a 66' CJ5 and by the seat of my pants I can tell when its time for a tune up by the way it starts and runs. Plus a rough idea based on the mileage since the last one.
Most of the parts that fail on a points type ignition you can look at and see the problem. Worn rotor contact, carbon streaks in the cap, pitted or burned points etc. Not so with HEI. You need a voltmeter and a troubleshooting book to tell you how to check what.
Just playin' the devils advocate so that you can consider both sides. Let us know what you decided.

Dusty, my mind isn't closed on this issue. But I mine is an 79 which came with AMC version of electronic ignition so I'm already in that boat! The hei would give me cheaper more readily available parts. I do agree with you about the simplicity of a points system. and heck I could carry a whole spare $60. dist!
