Well, the HEI conversion is so easy, I don't really see a need for myself to buy one from someone. Somebody that isn't comfortable with such things, on the other hand, may find it more relevant.
Of course, I run an MSD, with the factory components still in place, ready to plug in, for redundancy and a plug-n'-play HEI with instructions in the toolkit for myself (triple redundant) or a stranded mo-buddy.
