I have one from Craftsman, maybe 15 years now. Used it for everything from wood ship modeling, cutting exhaust pipes, to cutting screws in the chicken coop. She's showing her age though. Been abused, left out in the rain. Always does what I ask of it. She's a good friend.

I wish I could justify something like that.

I ended up buying a 400 series. Replaceable motor brushes, ball bearing and 2.0 amps. I didn't like the speed adjustment on the other models.
