I highly recommend Milwaukee. I bought my dad a Milwaukee magnum for Christmas once....VERY powerful drill




When built my super heavy duty subwoofer box, I used it to screw in 3" screws all the way into high density fiberboard (man does that stuff make a screeeeeeeeeeeech noise when you do that

). Never failed. Also as brainchild says, many contractors use them. This corded version was about $130.
Depends how much money you want to spend and if you want to have the tool the rest of your life
