Suspension upgrades for 99' A4

I just bought a 99' A4 1.8T quattro 5-speed. Originally I was planning on purchasing Koni coil-overs which would run $1,000. However after looking around I see you can get a set of Eibach springs for $240. I realize the coil-overs would perform better however I'm just looking for a lower ride height without much sacrifice in ride quality. Any advice would be appreciated.

Also, neuspeed has a set I can get for $190. I believe they specialize in Audi and VW parts so I assume these would be better than Eibach.

alot of people i know has gotten the elbilborck and had really happy results form it
