I got the 1/2 drive Earthquake XT kit for casual DYI. I probably could have made a better choice but I have no regrets. It does pack a punch and does everything I want it to from busting rusted frame and suspension bolts to popping nasty ball joints chucked to a C press. It laughs at lugnuts and stuff like that. Feathering the trigger to snug down fasteners is something you seem to get the hang of.
