In the days of Amazon (aka Aliexpress) that advice has to become more nuanced though. You still need a baseline of fitness-for-purpose rather than one-click buying a GENSYM Cordless Drill and thinking it might possibly suffice. And the traditional go-to of (brick and mortar curated) Harbor Fright has become somewhat expensive thanks to Trump's inflation, as well as increasing margins due to popularity (see also: Monoprice).

There's also just quality of life. As a DIYer I'm not particularly concerned about wearing out tools. But still I might want to pay more for better ergonomics, ecosystem compatibility, power, tolerances, or other non-longevity qualities, rather than being stuck with an adequate but suboptimal tool that gets the job done while bothering me.
