Vortech SQ. You can barely hear it until you rev it up. But here's the real question... WHY would you not want to hear that lovely blower whine? I loved my first supercharger- an A trim- it had straight cut gears and would sing at 10lbs of boost.
I like stealth. Just need to quiet the exhaust down a bit. The Corsa's sound nice but contrary to their claim I get the dreaded drone. The Corsa's will be for sale shortly.

I put a Pypes "Pype-Bomb" CB on my car. It has LT's, O/R H-pipe, and no drone. Nice and deep at idle. Not to terribly raspy, very subtle at the highway speeds where my Flowmasters would deafen me.
I know a few guys that ran those Powerdynes. They actually never had any problems with them believe it or not. There is also a belt upgrade that pretty much alleviates all the problems.
I outran a few powerdyne blown 5.0s back in the day with my HCI n/a combo. I wouldn't be surprised if they make competitive blowers, but I guess I've been biased against them since then.
