Good luck! I supposedly have a lead on another one, but it is already spoken for - Hans is getting it if I can close the deal. As far as prices are concerned, I have never seen one sell on ebay, so there has never been a big price on them. I got my three tents for about the original retail or maybe $50 over.
Larry got the original Chinese Imperial version of these tents on ebay, but the price wasn't crazy (probably because we have an unspoken agreement not to bid against each other, and this was before the high-bidding French and Austrailian E-Bayers joined the party).
