Milwaukee Tools is making a battery powered caulking gun. Uses the same type of 12V battery as a cordless drill or other tool. How frikking lazy can a person be to need something like this? I've never found a caulking gun to be even close to physically demanding to operate. In this day and age when we're supposed to be conserving energy, this is utterly rediculous, particularly at $230.00.
