Just retired from the MAC gig after 28 years. Harbor Freight can hurt your business a bit but most professionals don't buy the lesser quality tools anyway. They are in the service business and appreciate the service the tool man provides. I have my old tech school boxes from MAc as well as a Tech 1000 box that I have overgrown and I saved the MB1354 that I used on the tool truck. Those boxes will last a lifetime for daily users and a couple lifetimes longer for me.
