Princess Auto does sell mostly offshore, umm....crap, but occasionally have some very good surplus clearances on decent items. Craftsman, overall, I find to be similar if slightly better than Mastercraft, but not as good as Mastercraft Maximum. I've bought wrenches, for instance, from Sears and they are finished poorly on the ends and also have an uncomfortable grip which tends to cut into my hands on frozen/rusted bolts. I think they have different suppliers though, so maybe not all of their wrenches are like that. I also bought a 12" sliding mitre saw by Craftsman that I'd definately replace with a competitors saw in the future once it goes. My neighbour has the same saw, and the bearings get fouled up with dust and start binding. Mine has also become noisy after only a couple of years.
A person convinced against their will is of the same opinion still.
