There are a lot of epics that are BoE...Dwarven Hand Cannon...Krol Blade....etc....
P.S. Folks reported on one server of seeing several Krol blades on sale at the AH all by one person. Also this duping expliot was used to dupe a ton of gold from what I have read on many servers. On some servers people were giving gold away like it was nothing.
