superchargers... which one to get?

[1995MGTS]

Guess I need to get rid of the garbage in my engine bay. Just can't make any power with those little, cheap superchargers; see sig. :{
Anyway, for good reliable power, I would recommend Vortech. Seems like everyone in my car club has one. I hear nothing but good things about them. I was on a budget and got a very good deal on my SVO Powerdyne, brand new. So if money is a consideration, you may want to try it but you won't out power any of the other big three names.
By the way, I have almost 3000 miles on my PD, 19 dyno runs, and a dozen quarter mile passes without a hiccup.
