Best value 1/2" impact

IR guns are alright, though look for an older one made in the athens plant. When they went to southern pines NC they are not as good. ( about a 2 years ago)
If you can find a powerforce it was made by ingersoll rand and was more powerful than the 231C for less money. I had a 231 and the trigger froze up on the gun. Replaced it with a cheapy harbor freight Earthquake that I use about 10-20 times a year..its good enough for what I need. If I needed something better I would get the thunder gun...stay away from the titanium series by IR and the QT series by IR...they did not seem to hold up as good.
