Easy to change the height, and you can probably find some on the .org for the $200 range. They're a little stiff though compared to stock, so if you didn't mind paying $400 then buy a set straight from GC and and you can get the springs with softer spring rates (I'd say 230lb/in or softer, but not less than 120, and that should give you a sporty feel but retain some ride comfort).
