Maybe it was not intended as a 'marketplace' thread, as the idea of wanting to buy a rook cubimal but refusing to pay more than 10K for it is an interesting logical paradox.
So initiating a thread like this is more like going into the Chevrolet dealership and telling them you want to buy a 2012 Corvette but are only willing to play $6,000. That wouldn't be classified as marketplace activity. It would be Performance Art.
