I recently acquired a set of tubulars with ultegra 6500 hubs and Campagnolo Barcelona Rims for $75 plus $25 shipping. I've been given a set of Mavic GL330's. I would say this mostly points to a general lack of interest in non-carbon tubulars. If you wish to sell your wheels, find an enthusiast and sell them. Otherwise, you should expect similar pricing plus the hassle of creating a listing and shipping. I love the fact that one can acquire wheelsets like yours for a reasonable price. I'm certain the sellers feel otherwise.
