Not sure what all you're willing to sacrifice to get dex, but here's some ideas:
Head: Executioners Hood
5ac -- 5str -- 9dex
(massive ac loss)
Shoulders: Carnal Pauldrons
9ac -- 7dex -- 15 mana
Drops in SolB at royals, no drop, easy camp.
Feet: Dwarven Work Boots
8ac -- 3str -- 5dex
Easy to get but you're sacrificing a TON of ac
or, are you in a guild? The boots off zordak ragefire rot all the time
