I am in the market for a new buffer my old milwaukee has finally bit the dust. Any advice on a brand? which is best? I was looking at either the new Makita 9227CX3 7-in 10amp with a pre-set speed setting dial (from 600-3,000RPM) or the DeWalt DWP849X 7"/9" Variable Speed 12amp 0-600/3500rpm buffer. Both seem good and at the same price. Any preferences out there would be helpful. thanks
