Campagnolo never made 8s derailleurs in the newer (post 2001) versions. In 2001 when they changed the pull ration with the introduction of 10s, they still offered 9s, but not 8s. 9s cams come for both versions of the derailleurs but there is no 8s cam for the new platform, and Campagnolo's line is that the difference is minor enough for new derailleur to work with the old cam in 8s.
I agree that moving to 9s might be a good thing, but it isn't easy, needing at the very least a new cam for the lever, and almost certainly a new freehub body since the spline pattern is different.
If all is OK, look for a NOS 8s or 9s derailleur from before 2001 (best) or post 2001, (not as good, but OK). You can use a 9s derailleur for 8s because the indexing happens at the lever. You may not be able to find an older derailleur, but that may be a good thing because a newer 9s derailleur will work OK as an 8s now, while leaving you the option to upgrade to 9s when you're ready.
