Sorry for the late reply. I bought mine for $90 as well ($95 with shipping). I think it will pay for itself if I keep the Pathy for two years (I'm planning on 8 years though).
Get the AirLift 1000. It will stiffen up the rear and prevent some of the bounciness. Also make sure to see if the Radiator/Transmission bypass was done. If you are under 80000 miles you might still be ok. Read some of the treads writen here for more info.
