If you aren't in a huge rush and are willing to save some up the extra $$$ you could go with an entry level coilover setup like Tein Street Basis. I've seen them for $600.00 at a few websites lately (unfortunately CI is priced a bit higher than others right now). That's only about $100 more and then you are much more adjustable with your ride height if you want to go much lower later and upgrade control arms and what not.
Just an idea
I'm going to be saving money soon for suspension and Eibach was initially first on my list too but now that I read more about coilovers I like it more and more.
