The past couple years I have really been researching and investing in quality tools. Spend some time on youtube and watch tool review channels. Some great ones include: AvE, Bruce Allen, ChuckE2009, Garnett-Tools, German Too Review, Hard Knocks Forge, j young, Justin Dow, JUSTIN STURGILL TRUCKING, Koon Trucking, Real Tool Reviews, The HD Perspective.
With all the info I have gleaned here is some of what I have been buying: Knipex and Channellock for pliers, Wera for screw drivers (buy impact hard cap screwdrivers, they get used that way anyways) and allen keys, Mayhew for prybars, Trusty Cook deadblow hammers, Gearwrench, Sunex impact sockets (if you have impact sockets you often do not need a chrome set), Ingersoll Rand air tools. I have Dewalt 20v power tools, I now wish I had gone Milwaukee, they seem to have more tools, options, and higher torque ratings for their impacts (I still love every Dewalt tool I own).
Many tools are often rebranded, even the tool trucks will rebrand a tool as their own often with an increased price tag, so do your research. Quality aint cheap, but there is value in quality tools. Everything does not have to come from a tool truck to be a quality tool. I buy most of my stuff from Amazon and KMS Tools. USA (and Canadian) made tools are generally considered the highest quality, but European made (specifically German), and Japanese are of equal quality. For off shore, look for Taiwanese over Chinese made tools.
Warranty is important to consider, but when you're in a rural location without multiple mechanics working in one shop, you are not likely to see a tool truck pull into your yard on a regular basis.
For a tool box, I bought a Styrke box a year ago and I have been 95% happy with it. It is built by a Red Deer mechanic/farmer, he gets the sheet metal done in China (by the same factory that I think he said Matco boxes are done in) and then assembles them in Red Deer. Search for Styrke Industries on Facebook and Kijiji (Styrke is Danish for Strength). I bought it for the price of a smaller used Snapon box (72" vs 54"). The only things I don't like about my box is the drawers do not open to reveal the back 1", and the way the stainless top is attached.
