I bought my 930 in 81, for yrs I didn't even have it serviced and am lucky if I remember to have it serviced now knowing better. I haven't had a bit of trouble with it, have sewn things that only commercial machines are suppose to sew. I don't even remember to clean and oil as I should. This machine will never leave you walking. WORTH IT. Machines will come and go but that one will be a keeper. I have thought I would love a new machine, but can't see paying all those big bucks for a new machine when this one is so good. It does everything and all Bernina feet can be ordered if you want a special foot. Everytime I take it out somewhere someone is trying to buy it from me including the man that services it.
