I'm glad I'm not alone in my experiences.
Designing machines that are likely to be pretty reliable and long-lasting is not rocket science, and does not necessarily add much (if anything) to the cost. As with so many types of products these days,the thing most affecting price seems to be the maker's name written on it, regardless of the quality of the product
When I was at uni, colleagues studying engineering told me that one of the exercises they were asked to undertake was to design a machine that would work fine initially but was likely to fail after a relatively short time in-service. I gathered that that was not necessarily all that easy, but certainly gave the students some insight into the factors relevant to reliability and longevity!
