My Bernina lady told me that the 430, 440 and 640 are being discontinued. She said there are good discounts on them right now with the 430 being $1799 without embroidery, $2799 with. Is this a good price? Is it worth the price difference to get the 440? What do you like about these machines, pros, cons, likes, dislikes and what is different between them? Thanks is advance for your help.
