Well, I got sidetracked and confused and stayed with my Harbor Freight 1/2" "Earthquake" for now. I just don't use it enough for the desire to buy another impact gun that I won't use sufficiently. What I could really use is an electric one so I don't have to start the two-stage compressor just to pop off some lug nuts.
For the infrequent user, the HF earthquake is plenty of power and pretty hard to hurt. I have broken loose things and big nuts that should never have come loose.
So there I am, probably ready to buy a quality electric impact--maybe Makita--when the mood of the moment causes me to buy it.
