I don't know too much about these models, I know some have had their 20 year old Bernina in for service and repair, it has kept on stitching for years after and still do. Replacement parts are tricky for electronics, it can be done, but it's hard to tell when it's worth the time, money and effort. I'm not very against it, but it has to be worth it for buyer and those who had in their machines. Half the point is to get a reliable machine to a reasonable price that's up to the job. How good is the embroidery parts after 20 years? software, pattern availability, upgrades? How does it compare to a newer model? The very early coputers lasted a long time, some 1990s models still run. A hard disk from 1985 to early 1990s is slow and doesn't have much memory, but they still run fine. Even the motherboards\ and cpu tend to hold up. I doubt we can say that about the average hard disk today.
