I've had a lot of use out of my DeWalt XRP (18v) hammer drill. But it's not "light" by any stretch of the imagination. My brother who does contracting for a living now has two of them and managed to burn one out, something the service guys said they'd never seen before on that model. Replaced without question.

I'd buy a suitably-weighted Bosch or DeWalt any day of the week, but wouldn't use another Makita drill again (broke two of them, admittedly only one was a cordless).
