My 14 year old Dewalt 14.4 volt drill is on it's last legs. It might last for another set of batteries but for that price I could almost buy a new drill. Also the battery latch is ridiculously cumbersome.

Dewalt... works
doing floors I used a dewalt, I would go through a 50# box of 2-1/2" flooring a day at least 3 days a week for 5 years.
I Still have it.. it still works.
