[TwoHandedSword]

In Tarant, the Dwarven armorer ought to be a client for charged rings, as should the clothier next to the general store. And junk dealers (there's one by the docks) will buy just about anything, though at a reduced price.

Alternately, purchase expertise in Haggle and you can pretty much sell anything to anyone. It's so convenient that I almost never play the game any other way.
