By "truck brands" I mean the general category of tools that are sold primarily to auto shops via direct delivery by a guy who is trying to make an honest living. Obvious brands are SnapOn, Mac, Matco, and Cornwell.
I was just trying to point out that you will pay a premium for the "truck brand" tools as opposed to any of the "industrial" brand tools. The higher price is probably due to a combination of factors such as allowing a profit for the manufacturer, profit for the truck dealer, convenience of delivery, availability of unique tools for specific auto applications, and a name recognition/prestige factor valued by many professional auto mechanics. Don't misunderstand me ... they are usually good quality, reliable, tools and I don't mean to put them down ... they just cost more for, IMHO, no significant increase in quality.
What I call "industrial" brands are typically those that you will have to purchase at a supply house or on-line. Typical "industrial" brands are Wright, Proto, Williams, Armstrong, etc.
