I have a Milwaukee corded 1/2" drill that I busted the chuck on. Took it into the Milwaukee shop on W 8th? and they fixed it FOR FREE.
Lots of Porter Cable, and the most I have had to do with those, is replace the pad on a couple of sanders.
Dewalt sliding miter saw has cut a LOT of wood, and has gone through quite a few blades, still runs like a champ.
Black and Decker is junk. IMO
