I have had my Bernina 440 QE for almost two years and I am absolutely in love with it!! I know it is a little pricey, but boy is it ever worth it. Not one bit of trouble with it.
I bought mine during a promotion where I got the many extras for free like the embroidery module, BSR, and two sole walking foot.
My Bernina dealer is fabulous! I get to take free classes there for as long as I own my Bernina and all I have to do is call or email and she gets right back to me if I have an issue. That is almost as important to me as the machine itself!
But I don't regret my purcahse one bit. Now I am saving up for a Bernina 830!
