no question hands down the way to go...I had this on my wish list for a while and got it last x-mas...before that we used a Vermont American flush bit on regular or cordless drills and thought that was just fine...but let me tell you the upgrade was worth it...I should have bought it sooner rather than waiting for it to be givin  as a gift.  Its just is so much faster ...easy to dial in to your settings and light weight...
