I have two lightly used 060 belts. $148 new, $70 shipped each or $130 for both.
Also one Carlisle XS 817 brand new $75 shipped to lower 48, more to Canada or Alaska.
One of these belts is not as good as I thought. It has a cord on one side fraying and starting to come loose. Would still make a good spare. $100 shipped in the lower 48 for both.
