I got a 570 QE...the new one.....I don't know why Bernina reuses old model numbers...so to clarify...mine has the 9mm feed dogs, not the 5.5mm ones the old model had. Yes it is somewhat portable...I can lift it yeah! still is a bit heavy....and I ended up also picking up the little Bernina red machine to take to classes too....I am enjoying it...but it is a bit complicated to learn....there is a lot it does....and a lot to learn....but I am getting there...so if you get...make sure and take the classes that came with it...some things will be similiar to your old Bernina and some will be different....I had a Bernina 630 artista before this one ...so the 570 is a bit bigger for me....and there is a lot that is new too....I can use most of my old feet on the the 570 but as the 630 had 5.5mm feed dogs, there are some feet that I needed new....of course most of those came with new machine...and I do like the drop down dual feed foot...on the new machine.....
