I’m glad cheap stuff exists. Sometimes I really do need something quickly, and borderline-disposable quality is good enough. But I also want the option to buy better than that.
I installed some drywall a few years ago. I plan to install a room of drywall exactly never again. Not worth it for me to buy the best drywall tools.
But I have installed multiple wood floors, replacing old carpet, and would do so again if needed. I’d rather get higher quality tools there so I can keep them and reuse them for years.
