My Dewalt cordless drill died today. It's gotta be 10+years old. I marked the batteries when I bought them and the newest one I have for it says Oct 2010 and that was a couple years after my father bought it. It was a replacement for the one we burned out halfway through building our garage, definitely got our moneys worth out of it. I'm debating buying a multi piece tool kit with a drill, impact driver, reciprocating saw, circular saw, grinder, vibratory cutter and 3 batteries, but the $500 price is kinda hard to swallow. It'd be nice to not have to drag cords around for quick jobs though. It's $200 for just a drill and 2 batteries so I'm getting a lot for another $300, but that's still another $300.
