Loved my Bernina 440 also - and youre right - they charge enough for it - DH says the 830 is as much as a car and should have 'little people' in it driving it around!
I've had the Bernina just over 3 yrs but really didnt sew that much til recently - even now, I know I dont sew as much as many, because I also do a lot of hand sewing... Doubt I use the machine more than 5-6hr a week. I just dont remember what the warranty was, but it does sound like the repair place has taken action directly with Bernina - so I should have it or a replacement [I would hope] that works! ....someday.... :cry:
