Hey Bluemeate:
As long as the motor doesn't smell burnt, you should be good to go. Local tool repair guys should be able to fix it (if it needs it). I've done some repair work on the side and Milwaukee makes some of the best equipment out there. Even if it's broke, it's worth repairing (within reason of course).
As far as a screwdriver goes, I would go with the cordless Ryobi. I have had one of these for over 10 years and have beat that thing up! Haven't killed it yet. I had a Ryobi cordless sawzall but i dropped it and broke the casing. Taped it back together and that works for the most part. (just lucky on that one I guess)
For my money, Ryobi, Milwaukee, Chicago Pneumatic and Ingersol Rand are what I use. I also have been an industrial maintenance mechanic for for over 12 years so I have a tendency to buy stuff that will last.
Just my thoughts
