Yeah Nate, this combo was $199.00. The drill alone was $159.00, so the combo was a no brainer. There is a double life battery option available for $118.00, but it's twice the size of the stock battery, and the stock battery has a decent life.
My 36v DeWalt batteries are like $150.00 ea., and my 24v Bosch are over a C-note. Sometimes it makes more sense financially to buy a whole new drill, although that's not a very Green alternative.
