I take no cred it for finding this out juts remember reading it.
anyway for thouse of you who are still straped for cash at 55's+ and want to make some quick gold. there is a tower in western plaguelands that has some scarlet spellbinders in it that have a very high drop rate of the formula enchant weapon crusader. i think the drop rate it something liek 20%. i dont now how well this sells any more in 2.3 but i am sure it still sells well. sorry if this is old news but thought since i read all this stuff for nothing i would try to help out.
