I am going to play the devil's advocate. I am on prokit's and have been for about 4 years or so I think. Even with the smallest drop you can get, I am totally happy. My car rides very well, better than many cars do stock, without being stiff. My car is my DD, I have had low cars and didn't want to deal with it this time. For me, it works.
Now, I am starting to play around with the idea of going lower because I don't commute, don't even drive everyday, many days I put on less than 10 miles on my car. I am waiting to see where I end up job wise and if I stay local, I may go lower. If I commute again, I am staying with springs. The price difference is minimal though so if you have any urge, just go for coilovers. There were only omni's back when I bought my springs/shocks that were cheap.
