Just got the Bernina 440 QE a month ago and I am in Love! got my used with the knee lifter, BSR, walking foot and a bunch of other feet for $1900 including tax. Never thought I would spend that much on a machine (most of the cars we drive, didn't cost more than that), but I am so glad I did! Although the Bernina dealer is almost 1 hour from my home, they are fantastic! And they have a great reputation for service as well as giving great trade ins if you want to trade up.
I always feel that service after the sale in anything is very important, so if you like the Bernina dealer better, that is where I'd head. IMHO
Good luck! Having a machine that you are happy with and is a dream to sew with is sooooooo importatnt!
