ignition upgrade

i've got a '97 Prelude NA with i/h/e and i'm looking to upgrade the ignition for my next project. I'd like to know what people have heard about MSD products and what I should be shopping for. I'm looking to supercharge my engine in the next year or so, so what, if anything, should i keep in mind with the ignition upgrades?

Get a msd digital 6plus it is great.i went from SCI to 6AL now digital 6plus and it's best.it is equiped with a two steep rev limit with a 12v enguagement switch,a ignition retard controlled be 12v"nitrous switch"ect
or just a regular arming switch.high rev limit with soft touch,ignition kill,and can work on v6,v8 cars,ofcourse the tach output.and only$280.00
you can also upgrade and have a external coil.(blaster ss)
you might be able to do other things but that's what i did so just my two cents:comprage1

Check out the Cran cams HI-6 and HI-6s super street just did an article and dyno test on the system on this months issue check it out seems pretty impresive.
