I am not very familiar with the various systems, but I wanted to suggest that maybe you can be more specific about what you want in or mean by a "crafting system". There are systems for adding magical properties to weapons and armor, similar to Rizolvir's dialogue system in HotU or the various "gem" systems like Commanche's Slayers/Shadows of Darkmoon, or Scarface's. There are systems for customizing the appearances of weapons and armor, like Lilista's. There are systems for crafting other (non-equipped) magic items, such and Bioware's system for wands, potions, and scrolls and improved versions of that system. Etc. Crafting can cover a lot of ground. ;-)
I haven't explored the one in CEP 2.4, but I would think that others have and will know of different systems, too. But, it's usually best to give some context about what you are looking for as that let's readers feel confident that the thing they know about is actually what you want and encourages them to reply.
