Many tech programs have a deal cut with tool companies where the students can get 1/2 price tools. Many buy a decent starter set at 1/2 price and build on from there.Can a mechanic making a living at a dealership or indie shop make enough to justify high end tools? Has the cost of tools gotten away from income?
OTOH, if you can afford nice things and appreciate the feel of really good stuff buy it!
If a kid coming out of school wants to have the big nice tool box and all the fancy gadgets they'll be in a world of debt real fast. I've seen that happen many times. I've also seen some of the best techs using an old Craftsman set they got in high school with only name brand specialty tools added on or broken tools replaced by the big name brands.
A top of the line Senior Master tech in my area can pretty well name their price as they tend to be leaving the industry for greener pastures(fleet maintenance, computer programming, industrial maintenance) with no one left to replace them. So they can afford what they want but the ones I work with or keep in touch with from previous jobs all watch their spending as they are already planning their exit from the dealership world.
