As a professional tech over most of my adult life this is what I've learned.
Things that must be Snap-on.
Wrenches, chrome sockets, universals (both impact and chrome), 1/4" drive ratchets, and air ratchets, drive bits (torx, allens ect...).
Everything else either Matco, or Mac.
All other air tools (die grinders, impacts, ect...) Ingersol Rand no doubt here, there are no substitutes, even Snap-on isn't up to par in my mind as a good ol' IR air tool. Matco's air tools are mfg by IR FYI.
Gear wrenches are awesome, not mfg by any of the above.
Makita drill and flashlights are top of the line.
Snap-on really small cordless driver, best 125$'s I spent last year.
Snap-on cordless impact, with out a doubt will take any rusted on lugnut off, even better then my 1000 ft lbs IR impact, have broken lugs with this thing.
Tool box's are just box's I would suggest getting what you can afford that is big enough to hold all of your tools, I had to buy a new box last year because I had no more room and the new one is already full, 5k$ for the new box too even though its a Matco, same size for Snap-on was like 8k$.
