The Makita and Dewalt Li-ion stuff is crap. Milwaukee has a patent on the technology, and the Li-ion tools have been in development for 6 years. They are expensive, but everything so far shows that it is a superior technology.

Makita just wanted to build the same weight tool, with longer run time. Dewalt did the same. However Milwaukee built theirs to be the same weight tool, with 4x the run time, and greater power. Thats why they are able to provide a cordless bandsaw for the first time.
Secondly, Milwaukee tools are better built, and last longer to begin with. All my tools are Milwaukee except for my Makita 10" compound sliding miter saw, and Bosch 1" rotary hammer. They get used daily, abused, and they still look and function like the day they were bought. My grandfather trusted them, and some of the tools I use he bought new before any of the other companies existed.
Milwaukee are also the only tool manufacurer left in the US, and they intend to stay in the US.
If I were you, I would stay away from the Chinese crap, and buy Milwaukee. But remember, they are not for the average joe, hanging shelves in his house. They are built to take the abuse of daily work in a hostile enviroment.
