Bilstein Coilovers. I have the B16, but the B14 for the price is not far off from a shock/spring setup and allows you to change your ride height, which is worth its weight in gold.
That's why I went with the B14. It wasn't all that much more than a shock/spring combo and I get to set my ride height exactly the way I want it. Plus its an actual German made part...if that means anything to anyone.
