I have 3 berninas and love them all. They all work great and I haven't had a moments trouble with them. One is a 830 record from the seventies, one 180 artista six years old and the newest one (to me), aurora 440 with the built in BSR is a couple years old.
I also have a three year old mid- range memory craft janome that is a little work horse. Originally I had a old dressmaker singer, and it worked fine.
I also have my mom's old "portable" singer with a rounded wooden top on the case. It was made january 15 th 1951 and she used it until she passed a couple years ago. Those babies had every foot imaginable and went and went... It doesn't matter the age of the machine really. It is whether or not you love it and it functions for your use.
