Sears has a special on Craftsman 1/2" air impact wrenches for just $21.99! (normally $59.99) It puts out 400 foot pounds. Not the best but for just $22 who can complain! I ordered one while I was ordering my Grandson Case some tools. His Dad and I are starting him a tool collection so when he's older he'll have a bunch of tools to kickstart his wrenching days. HERE is a link to the air impact.
