Well, running a quick search for "Mongoose" yielded
Enchant weapon: Mongoose. It drops off Moroes in Karazhan, at <1% drop rate. And it increases agility by 120, not 100, and gives a slight boost to attack speed; I hear it's about 2% at level 70.
By the way, anyone know how to link the items so they pop up when you scroll over them? The old way = teh suXX0r.
