The last time I "upgraded" my machine was well over 5 years ago, and it wasn't a new machine but a trade in. I also have my serger that I bought in 1982, it still works great, although I don't use it very much now, but it's has a ton of miles on it. I don't plan on upgrading any of them, but do hope to get all my "antiques" up and running one of these days. Also, the first and last new car I bought was 1972. LOL
