Definitely one of the better videos I have found out there about these drills. I still haven't pulled the trigger on one, but this gives me more food for thought on not just the upfront cost, but the cost over time. For me, and I know many of you, downtime is costly time. Something is inevitably going to break and to be able to repair w/ reasonable time and effort is important. I liked their suggestions on proactively addressing some of those potential issues and the tips on maintenance.
