My mother has had a Bernina 830 for 35+ years, and I just bought a Bernina 730 which is about 10 years older than her machine but I loved her machine so much, it's what I learned to sew on and it's needed very little maintenance through the years. I plan to make the 730 my main machine when I get the new belts (on order). If the 630 is anything like these, I say go for it.
