MSD or not

Looks like opinion is polarizing - either like MSD or you don't.

I don't trust my 6AL box. It failed on my car within 100 miles. It was just up the street from the house and neighbours pushed me back to the garage so a bit embarrassing. It was off warranty as installed quite a bit after I bought it. Sent it to MSD and they fixed anyway, without cost but wouldn't say what was wrong with it - so I assume a manufacturer issue.. Problem is - I am in Canada and took more than a few weeks to get it to El Paso? and repaired and returned.

So, every time I go out, in the back of my mind I am wondering if the MSD box is going to crap out. Many say - keep a spare in trunk. But these units are $400 or more here and I fundamentally think that if I have to keep $400 spare part in my trunk I should question why I am using it! Having said that, i already have it and maybe I will look for used one.

On the other hand, my brother who builds quite a few mopars swears by them and has had good reliability from them.

If doing over, I would look at something different, that I can find/replace locally at more reasonable price.
