I picked up a set of the SAE for my Dad for his B-Day. I was sorely tempted to pick up a set of the metrics for myself but I resisted. Looking at them now.. man, they're nice! Lightly oiled, high-polish chrome finish, smooth ratchet action. Looks like a good set.
Interesting warning on the back of the box: These tools are not intended to free frozen fasteners.
The first set I walked to the cash with had a 10mm in place of the 3/8". I got another that had the right assortment. Must have been packaged on the drunk shift.
