you must be able to get cheaper " own brands " ( I must admit my knowledge of US power tools is limited to the main brands, slight funny side story , I got Married in Vegas, middle of our trip, We are in a Vegas tool store buying a Dewalt 14.4 v Cordless drill and 2 batteries , had some funny looks when the batteries were in the hand luggage )
its not going to be hammered ( no pun intended ) so a own brand would be fine, and if it does die inside a week, just return it
though that will slice them off easy enough
