If you are looking for a comfy ride, then you should consider the Tein CS or Flex. Or, if you want HKS, HKS just launched the Hipermax LS Plus, which is basically a comfy tuned Hipermax II, with adjustment for stiffness. The normal LS does not have this.
If you do not care about this feature, you can also consider Apexi WS. I have them and they give a very good ride and can be lowered a lot. I only paid about USD1000, including installation.
By the way what rim sizes do you have? The rim size will have a big influence on your ride.
