Rzr s Fox... rebuild, or replace ?

I have no complaints from my S fox shocks.. but when I walked into
The shop today, I noticed a puddle of oil under the front shocks.

I'm not sure how long its been since these were serviced, and If I
Do rebuild these I am sure I would want to go back with racer tech
dual rate springs.

Sooo... my question is...

Should I spend the 800 or so to rebuild and upgrade the springs

OR... Is there a better option out there for around the same dough?
