Personally I also use one of these and an EoTS. Mosquito Eye is nice because not many droppable caster items pay attention to STR and AGI, both of which are nice to have--since many nukes will not land on "uber" mobs unless you are in melee range... So I will take all the AGI that I can get for the times when they try to bite and scratch back. And 5 AC and 65 mana is damned nice to wear on your ear =)
