I have a variety of tools, even a couple of Harbor Freight (gasp) in my tool boxes at work and home. Ratchets and screw drivers are the two tools I absolutely refuse to own anything but the best. I have Mac and SnapOn at home and all SnapOn at work. Both screwdrivers and Ratchets.
I have to say that the little shorty wrenches I bought at HF to remove my headers have REALLY came in handy on the mechanical work. Swapping out the Proportioning valve.
