I absolutely agree with you BrewBeemer.
Milwaukee is king when it comes to power tools.
That die grinder you are referring to is a "real" beast. I've used that grinder for years working as a pipe welder.
For these guys I would recommendhttp://www.milwaukeetool.com/tools/metalworking-and-grinders/grinders/die-grinders/45-amp-die-grinder/5194
It is much smaller with all the power one would ever need for brewing projects.
You can grab a used one off ebay for not much than that B&D crap.
Plus your grandchildren will still be using it after your long gone.
