When I started buying tools over 30 years ago, I asked advice on buying tools from several tradesmen from my hometown. Almost to a man they all said Milwaukee was the way to go for the following reasons:
1. Parts and service are available all over North America.
2. They can be severely abused and keep running.
3. They use common parts that can be replaced. The Magnum series have replaceable/removable cords.

All of the Milwaukee's that I bought are still running. I have replaced cords, chucks and such to maintain them. I am not knocking the other brands such as Makita, DeWalt, or Porter Cable as I have some of those too. The problem I find with those is they change models and parts get hard to find. The Milwaukee's are heavy and robust.
Almost too heavy but I am willing to put up with that as I have never replaced one in the middle of a job. I don't like their cordless equipment but the AC powered equipment are worth the money.
