Adept III's are made from rares. This much we know (or you do now). Tier III rare- Rough Jasper is going for 12-15gp on Neriak as of Dec. 2004. Needless to say most people may only have 1 adept III per tier as it seems you will out grow it before you get another 14gp or find another rare.
Here is my question: What would you propose as the must have Adept III? You can break your answer down by tiers if that makes it easier.
