Furniture auction sites?

Does anyone know of some good design/furniture auction sites? I am looking to sell some classic Steelcase task/desk chairs, and Ebay is worthless in this arena.

I have to say that i disagree with you on this one. I frequent ebay and its furniture auctions, and I see both great deals for buyers, as well as sellers getting way too much money for what they have. Its all about the way you list your item so that you get the correct hits. I think that ebay is so commonly known that it is your best bet. You can also set it up as a live auction, if you want to sell it in a live auction and incorporate ebay users.
