Anyone try these distributors?

I wonder what slantsixdan's opinion would be on this as he is an "electrical expert"...and I "think" but not sure, he states a few times the gm hei is junk....Not trying to stir the pot at all, just simply wonder what his thoughts are as he has had some valid points in some of his reasoning's.., and although he might come off as a "know it all"...
