MSD or not

I have also gone through three MSD boxes, the failure rate seems to be high to me but as previously said when they're working they're a great unit. But they are a little spendy so I went with the Pro Form Chrysler ignition designed ignition and really liked it for the street. Very economicalCombined with a High Rev aftermarket control box it's a good little set up. The curve Springs were a little light for my liking but that was a $6 fix. But I swear by their coils. And that's a lot better than swearing at the coil:)
