For home stuff I usually buy Black and Decker. Circular saw, jig saw, 1/2" corded drills, DA palm sander, and 5" grinder. None have given me the least bit of trouble, and the 5" grinder I actually used at work (fab shop, plate/structural/machinery) for 4 months or so. I never once smoked it, it still runs strong as hell too. It owes me absolutely nothing. I was issued a heavy 5" hitachi at work, which I subsequently ended up sending for repairs twice already. Once for trigger (happens) and once for brushes already. I have approx the same amount of use/abuse on that one as I did on my B&D. Do get the paddle trigger no matter what brand you choose. It's safer.
The lone exception is my corded DeWalt sawzall...
For home use i personally feel it's hard to go wrong with B&D, based on performance versus outlay and longevity.
