MikeB yep on the Milwaukee for sure. I have screw guns, hammer drills, drills, and two saws of which the oldest is over 24 years and all that has been done to any of them is replace brushes, cords and triggers. They used to get used everyday, though I haven't been in construction on a regular basis for 11 years.
PortaCable made some solid power tools also...
I 've a mix and match of Snap-On, MAC, SK and Craftsman all f which carry good warrenty.
