I work in the building trades in Manhattan NY.I asked a sheet rocker what was the best gun and they told me dewalt. I figures why buy a new one when my old gun still worked. The old gun burned out and I had to run out to buy a new gun. With the advice I previously received I picked dewalt, It worked smoothly and quietly and within the hour I had wished I tossed the old gun working or not...this gun is well worth having.
