I recently purchased a Bernina 440 QE. There are two reasons I choose Bernine. 1) The quality seems to be above all the rest and 2) the BSR. I also have a Singer QE and of course a Featherweight. I don't have to worry about lugging around my Bernina because I always take by Featherweight when I travel.
The other reasons I purchased my Bernina is the sales people were very patient with me and took their time with me much more than the Jarome people. I knew how to work the machine before I put any money on it. The people made the difference, and of course the BSR.
