Pretty sure Koni's are usually rebuildable. Also pretty sure, it wouldn't be cheap, but a whole lot cheaper than buying new ones.

If the shocks aren't leaking, and move in and out, I can't imagine that they aren't as good as new, unless they are gas charged, and some pressure has leaked out. If that were the case, I'd think there would be some hydraulic fluid leakage.
