I think Olivetti was the last major company still making manual typewriters into the 1990s, but those had been so cheapened down they had a terrible reputation. The all plastic "Royal" I found can'tbe the original Royal company, has to be someone using the name.
I think the trick is to buy a rebuilt vintage machine from the heydays, roughly 1930 - 1965, when they were still making precision machines built like tanks.
