If you're buying tools for professional use; AVOID CANADIAN TIRE AND PRINCESS AUTO AND HARBOUR FREIGHT.
CTC sells a "professional" wrench set that goes on sale regularly for $49. The only Mastercraft tools I own. They're
almost as good as Snap-on. (The older ones are better. The new ones they tried to copy Snap-on's "flank drive"... it didn't work).
You're going to need some 6 point sockets and wrenches. Something CTC and Princess Auto doesn't sell, so you're going to have to buy SK or Snap-on.
A 15mm 6 point Snap-on wrench is $47 USD
Almost all tool boxes in Canada are made by Beech (not Snap-on. They're made in the US)
Snap-on makes the best ratchets (A tip: when you buy a decent ratchet get them to throw in a re-build kit for free. It may save a job later in life)(... but I can almost guarantee you lose it before you need it).
A cheap "beam" torque wrench is as accurate as anything else you're going to use in a garage setting.
You don't want/need air tools anymore, the cordless electrics are that good and cheaper and easier to use.
Used tools are usually a good deal. Old stuff is usually better quality and you get better stuff for less money. Old Craftsman (from Sears. The new stuff is crappy Stanley/Black and Decker) or Proto or Westward is as good as Snap-on for sockets.
Buy the best BASIC tool set you can afford. I'm sure I could put together a decent basic tool set for a motorcycle apprentice for $1200-1500.
Most shop mechanics will NOT lend you tools... more than once. If you need it a second time BUY ONE.
When you NEED a special tool, buy it cheap. If you break it, buy a better one. Nothing like spending $500 on a special tool, only to use it once.
One of the best techs I know works out of the most ghetto tool sets I have seen. When I go to his shop, I bring a tool box.
I also know a tech that has more money in his tool box than I have in my house.
Tools are an investment. I own tools older than me.
... a secret they don't want you to know: Snap-on/Mac tools aren't necessarily BETTER, the reason Snap-on and Mac are popular with mechanics is the tool store came to the mechanic... and offered credit (at usury rates). DON'T BUY TOOLS ON CREDIT
