I don't use my personal tools on the job site, so Sears has always seemed to be just fine for my at home jobs. I like the new Milwaukee's with the Lith-ion battery packs. They are tough as nails and light weight. I've never had any trouble with the Dewalts either. It's too bad I just bought a couple more battery packs, since I'm not planning on using the Carftsmen drills anymore. Oh well, I guess I'll have plenty of batteries for my sawzall and circ saw.
