I have Craftsman, Snap-on, and even a few Mac tools, and I gotta vouch for them (Craftsman). I work on heavy trucks, and I beat the shit out of my tools when needed. The Craftsman stuff keeps coming back for more, though their ratchets could be a little tougher. For those, I've had good luck with S-K, Snap-on, and (believe it or not) Husky.
