Sears offers the Craftsman Universal Miter Saw Stand, model no. YH-MS029A, for $59.99. Coupon code "SEARS2014" cuts it to $54.99. Choose in-store pickup to avoid the $21.59 shipping fee. That's $40 off and the lowest total price we could find, although we saw it for $6 less in June. It features brackets that fit most 10" and 12" miter saws, support arms that extend up to 80", spring-loaded support legs, adjustable height, and support for up to 330 lbs.
