(I need to make a Tools magazine to ask questions in) Harbor Freight Earthquake series. Their stubby is actually decent https://www.youtube.com/watch?v=jqWypTAG4Hw -A Used Chicago Pneumatic, not to be confused with Harbor Freights Central Pneumatic. They are $50 used all day, reliable, and can be rebuilt. https://www.youtube.com/watch?v=KTdKYtqO94I https://www.youtube.com/watch?v=GzRlXSIMeeQ AIRCAT 1150 if you want a lot of torque. Small premium over the Harbor Freight offerings, but more reliable.
