2000 GMC Jimmy Supercharger Application Recommendations

I own a 2000 GMC S15 Jimmy (2WD Diamond Edition to be exact) which has a 4.3l engine with a distributor. To my knowledge, the 1996-1999 models of this vehicle do not come with this distributor straight from the factory. I am in the process of searching for the ideal supercharger application and I have only been able to find 2 possibilities from 2 separate companies: Powerdyne and Vortech. Originally I was considering the powerdyne kit because of it's mere $2300 cost and 40-50% horsepower gain. It's a centrifugal internal lubrication system with ceramic bearings. I have read other forums which lead me to believe that powerdyne is not the way to go (such as the belts and bearings going bad, only 4 pounds of boost being blown as compared to it's claimed 7 pounds, and in some cases it was not functioning at all). So that left me in search of a more expensive supercharger by Vortech. Their kits go for about $3,350. Well see here is my new dilemma: they only provide kits for year models 1996-1999. The reason for this is the simple distributor that comes standard on the 2000 and up models. I spoke with a tech from vortech who told me that I could try out the kit at my own risk and I could not return it back if it did not run properly. He did however mention that I could manipulate the mounting brackets so that it would not interfere with the distributor, but that the supercharger would still not be guarunteed to work properly. My first question is do you happen to know anyone who has attempted any type of turbo/supercharger application on a 2000 and up Jimmy/s10/sonoma/bravada/blazer? If so, which application did they use and how well is it running? Secondly, do you know of any other supercharger manufacturers that supply a kit for my application?
