Sears offers the Craftsman 50-lb. Sandblaster Kit with 1/4" Ceramic Nozzle, model no. 16706, for $53.99. Coupon code "SEARS2014" drops it to $48.99. Choose in-store pickup to dodge the $8.99 shipping charge. That's $11 off and the lowest price we could find, although we saw it for $2 less last week.
