ZZR250 suspension

Hi guys
Just tidying up a cheap & nasty ZZR250.
Suspension front & rear is pretty average (read: stuffed) - my current plan is to replace the complete rear shock/spring unit with a good one from a later/lower k example, and I've spoken to a suspension shop who has suggested about $500 for a proper overhaul & revalving of the front.... or $140 for new fork seals & fluid.
Thoughts/suggestions?
And yes, it needs doing as it bottoms out.
