The Performance Brand is available at some of the MacParts places. Kragen I think? PepBoys has some, but they seem to be rotating over to the Stanley brand.

You most likely would find the Performance Brand at an independent auto parts store. They are not super high quality, but for the occasional tool that you might need to modify :-0 they work OK. Much better than the chinese Allied brand that you might find at Walmart or Target.
