CCK from Taxonomy?

Hi. I was wondering if there is a module that provides me with the functionality to add fields to a taxonomy term like CCK does for nodes? I've noticed that there are quite a few modules in the Taxonomy module section but to try them all out will take forever.

If you know of a module that provide this functionality can you please share your experience with that particular module, like to pro's and con's? It will be very much appreciated!

Thanks,
Luke
