Check out the drow spider silk armor in the recent drow issue of Dragon. (cant recall exactly what issue number, but I'm sure soemone on the boards could tell you). It has a +3 armor bonus and a very high max dex, in addition it only has a 5% arcane failure. Really ggod stuff from high dex fighters, rogues and fighter/mages.
My drow NPCs make extensive use of it.
