I have "tennis elbow" in my left arm, and my current cordless drills...both 24V BlackMax drills, are way heavy when I'm using them. Their total weight with the battery is 5 lbs, 12 ozs. Someone had a Milwaukee 18V recently in a seminar that looked light. I'm not looking for "cheap" cordless drills, just lighter and powerful drills. Thanks in advance for any assistance in identifying what I am looking for.
