I need to drop my ride!

I need to drop my integra, I was thinking of getting some skunk2 coilovers. But I don't want to have a bumpy ride I want them to drop the car but at the same time to be stiff. should I get springs or coilovers? I don't have alot of money to get the real coilover kit ($800), can somebody please tell me of cheaper alternative. Are springs and coilovers hard to install?
