I have a DeWalt angle grinder that has taken a wicked beating over the years and is still going strong.
My miter saw is a Craftsman and it's pretty solid. I don't feel like it's as nice as my DeWalt though.
I've also got a set of the ryobi battery-powered tools and the batteries kind of blow. You'll probably want 3-4 batteries total if you use them often, and they are pretty expensive, but if you are only the occasional tinkerer you should be fine.
