That Dewalt impact is a good deal. Have the same one and it's got loads of torque. Good luck with the sale.
i got it from a guy who buys unclaimed storage buildings super cheap. all my stuff is milwaukee but i couldnt pass it up at the price he let me have but i buy alot from him so he does take care of me.
