I guess I should start off by saying I love my Bernina machine(s) that I have owned. I love the way they sew and I loved my 150 for quilting. I had decided to give Viking a try and while I liked the way it sewed, I didn't like it for free-motion quilting because of the shape of the front of the machine - I couldn't see what I was doing.
Now that I have the Bernina Aurora 440 QE, I decided it was time to give the regulator a second try (I had test driven it when it first came out). My impression is still the same....... I don't like it. I have been told that if you learn to free-motion without a regulator, trying to use one is nothing but frustration. I totally agree. I know that when I go to a quilt show and play on the long arm machiens, I always asked them to turn the regulator off.
So while I love the way Aurora sews, I won't be using the BSR and it will be sleeping in its little box in the drawer. I do know one thing........... if I tell hubby I want to change machines again, I'll be sleeping out in the garage LOL
