I'm in the same boat. I like the firmness and lowered ride of coilovers, but I really liked the OEM ride quality. I've heard bad things about springs (including Epics) on stock struts though. They seem to blow out shocks quite quickly. IMO, if you want to be able to corner, without body roll, and without hurting ride quality, you should go with sway bars and endlinks before springs/struts or coilovers. Sway bars will drastically affect handling without really changing ride quality at all.
