MSD yay or nay

I like the Pertronix Digital HP CD box. I installed one in my truck about a year ago and it's held up great (overkill for current engine but I do plan to upgrade). It's physically much smaller than the typical MSD box but comes with adjustable 3-step rev limiter and keeps multi-spark all the way to redline instead of reverting to single-spark above 3500 rpm or whatever like an MSD. Price is pretty good too for what you get.
