We all know you get what you pay for.
For the best answer to your question, my money is on air ride shocks. Back in the day's, airbags were looked down upon by performance enthusiests, but the technology has grown up since then. The will provide you with the handling you want and you can dial in your height from inside the car...PLUS you can raise or lower your car as needed (towing, speed bumps, etc.). Now, if those are too rich for your blood (and mine), go with a set of true coil overs, NO SLEEVES. The sleeves are bad for teh shocks and most of the time people get the wrong springs to match the shocks. A full coil over set up will come with shocks and springs that are matched for your ride and purpose. QA-1 and JIC are the best I have found so far, and they will make sure you get the right setup for your car. JIC's are unique in that the ride height doesn't effect the shock travel.
Hope this helps. Personally, I run Eibach Sportlines with tokico shocks and have no problems.
