The AH on the Alliance side is empty things mostly sell just above vendor price. How is it on the Horde side?
Last few scans I did were between 1.6k and 2k items on there. Can usually find anything I need. Lot of undercutting with small amounts, but in general it seems pretty healthy.
If you go to Gadgetzan There an AH there for both Horde and Alliance may have luck there?
