Whats the difference between these two? Mastercraft and Mastercraft Maximum? Are they better quality then one another or they are just different names that they charge one more then the other? I have recently receive our Canadian Tire's flyer and it seems like they are still selling some Mastercraft tools. I have spotted a 40piece screw driver set from mastercraft for $49.99 and i was wondering if it was worth it ( they don't seem to have that quick snatch that you men/women been talking about).
