Man screw Craftsman. I say Mac, they will work with just about anyone. You can usually walk up to a Mac truck in the lot of a dealership and they will sell to you. Craftsman tools are ok, but most are hard to use for long periods (wrenchs will HURT your hands). I wrenched for about 12 years, Snap on has my vote for most everything but wrenches...Mac tools fit your hand. So I say buy all Mac Tools and split the difference, but Sears Tools are just OK.....
