I have a Correcting Selectric II. It was my typewriter for more than 22 years as a secretary. When my employer went into PCs, it offered some of the typewriters to the employees. So I took my Selectric home. It worked for another 10 years. I still have it, but it needs work and I can’t find a repair person around here. I loved that machine and still do.
The last major typewriter manufacturing facility closed in 2011. Typewriters are rumored to still be manufactured by one or two small companies but it’s essentially a dead technology. We spent one summer looking (successfully) for a manual typewriter requested by an Italian monk. How long he’l be able to get ribbons for it is anyone’s guess.
