So far what I've seen is that ride quality is going to suck no matter what. You can do things to improve it but it's not going to ride like a Cadillac, unless you spend quite a bit.

There's a great suspension guide by Jazzer, and here's a great guide too where you can study and gain an understanding of how to attain drop+ride quality.
