nah man reco-ning shocks will cost way to much. just save a bit.
its not just oil, they are gas pressurised as well. in fact im not sure whats in there, but its expensive and un DIY'able.
note: i try and do everything on my car, and im like you and are stingy and hate parting with money on things that look easy to fix, but unfortunately with shocks you just gota bite the bullet, no easy way out (otherwise i would have found it by now)
