Here's one that I just tried out last night that I'm very happy with:
The Complete Craftsman
For those of you who like the crafting system in NWN2, you will be pleased with this one. It adds a huge number of new enchantments and items to the possible recipes plus the ability to breakdown magic items into their essences and gems. You can also put restrictions on your items to give yourself additional enchantment slots. Pretty nice mod.
