I love my Bernina so much I bought another one! I have the 440 QE & the 330, I use both and have them serviced once a year. I had Kenmores before & if I would have had them serviced more often they would still be with me now. My daughter uses my Kenmore that I bought in 1994 but I threw away the one my dad bought me in 1969 & I am still kicking myself for that. Stupid, stupid, stupid!!! Service your machine & they will keep running forever.
