I can buy an expensive tool for say $200 that will last me 10 years. Or I can buy a cheap tool that costs $20 but will only last me two years. But if I want to use that tool for the duration of 10 years it then makes more sense to buy five of the cheap tool and save half in costs. Which one is really providing more quality over time?
For some things this doesn't hold at all, the cheap entry level offerings just don't get the job done or break relatively immediately, but for others the premium offer doesn't really improve a whole lot over the cheapest.
