I'm just trying to get info on the jackson racing sc's. I've heard some people say negative things about them, so I was just wondering, are they worth getting?

Reliability, power gain, etc. It seems to be a cheaper alternative to a turbo, and possibly easier on an engine in the long run(?) Can anyone give me opinions on these things? Btw I already searched the forums to get bits and pieces so dont blab at me for posting =p

Add: engine has 96k on it
