Mark - Keep your eye on E bay there has been a few adds from Calgary Alberta dealers selling stock tires that customers traded in for a upgrade when they bought new. The ones I saw were going pretty cheap. I am pretty sure it was GW Cycle in the north end that were moving them. I might be worth just phoning some dealers, if they move enough Rincons and the buyers upgrade right of the bat with their tires you may find your self a good deal.
hope this helps
