Trying to figure out whether it's worth keeping an old bike on the trail or finally sucking it up and buying a whole new bike.

2000 Judy XC fork is leaking oil. Can't find a rebuild kit for this model (have read that some other kits "might" work, but no guarantees).

Knowing that products get better over the course of ten years, what current fork would be comprable to the old Judy? Dart 2, Dart 3, Marzocchi 22, other? I don't need to upgrade this bike; would just like to keep the same level of performance (or lack there of as the case may be).
