the mastercraft maximum range are mostly made by various divisions of Danaher - according to the back of the pacakage.
The Mastercraft Maximum torque wrenches are good. Plus our local stores have gone crazy for the last three months with 50 and 60% of sale items. I just bought the 1/2 inch drive impact 7 piece Torx and 14 piece SAE/metric hex set for $24-99 per set. All have a lifetime warranty.
The local Brafasco carries a large selection of Armstrong tools and three of the local industrial suppliers carry Gray tools.
Also check out NAPA they carry a huge range of tools - not just their own Ultrapro. Our local NAPA store is attached to the South West ontario warehouse so they have everything you can see in the online catalogue available. It is hilarious when you go into the store and they say sorry we don,t have that item in stock we have to order it from the warehouse. Ten minutes later the part appears through a hole in the wall in a blue box on a conveyor belt and then they just barcode it into the store. Ours is open seven days a week until 7pm Mon to Fri. The link for their tool catalogue is below they also have a monthly sales flyer that you should check out on line.

If you contact snap-on or Mac they will also give you the phone number for a local dealer. If you check out their catalogues on line make sure you check the canadian website because the pricing is very different to the U.S. site. I just bought the snap-on 1/2 drive hand impact it cost $74 plus tax which is more than $20 more than in the U.S.
I've used Gray Tools for over 25 years (ratchets, sockets, wrenches, etc.) and broke a couple of chrome sockets due to me using it on a impact gun for many years and a wrench due to a cheater bar for leavage. But in the same breath, I've broken many Craftsman, Proto, Husky, Stanley etc. Never had a problem with their warranty. Walk in with broken tool, walked out with replacement in my hand. I'm not saying they are the best tools around, but don't knock it until you've tried it. Their polished wrenches looks and feel better than some Snap On/Mac Tools. Very reasonablely priced too. Stores that sells them always willing to haggle with the prices so never pay retail. Source One Tool Trucks will give you a great deal too.
