I've seen the Bilstein PSS9 Sell for as little as $1500. I paid $1800 for mine.
Sammy is right though, if your not tracking your car you can really get away with just springs and shocks. If you want it for the ride height adjustment is pretty useless, I find it a pain in the ass to adjust. If only the had a system that can be computer adjusted from inside the car, now that would be sweet.
Look around if your really interested in the Coilovers, there are always pretty good deals out there. I definitely wouldn't pay the MSRP of 2300.
Oh and for the install Blinkwatt is right, its gonna run you close to 1k.
