If you can return, I would simply based on cost. Generally you don't want to pour money into something that isn't going to give your dollar back in performance if that makes sense. Everything beside the fork is probably fine, so if you have to spend money you could simply replace the fork. Bike co-ops usually have similar quality ones around if you have access to one.
Keep in mind that the fork can have a dramatic effect on how the bike handles, so you want something as similar to the original as possible. Also, you're looking for a 'threadless' suspension fork. Avoid 'suspension corrected' or high travel suspension forks, though all of those will probably be way out of price range.
