Sounds like the same age as my 440QE and every time I think about upgrading I think why. I have mine cleaned every year because I sew over a million stitches each year and every time it comes back it sews like I it time the first time I took it out of the box. I also have it cleaned each year because a good friend of mine is a Bernina tech. I have the embroidery module but only use it one or twice a year to personalize something for the holidays, some years I don't even use it. I recently sewed on a new Bernina which is going on sale shortly for $1000 and while it is a nice machine with no BSR it is definitely not my 440 QE. I have always loved it. I am guessing since they don't clean it often it wasn't used much. Good luck in deciding.
