I purchased a used Craftsman 12" band saw last week, including the stand. Sears offers a caster set for the saw but at $118, that is more than I paid for saw. As for the availability, that could be another story. How can I determine who manufactured this for Sears ( band saw 113.248321) to check on availability of the casters from the direct manufacturer? Would a tray that sits under the stand (including the rubber feet) be a better idea? TIA, Ray
