I like to quilt larger quilts on my Bernina 1230, its a work horse and never gives me any trouble. I like to piece on either my Viking Designer I, or Viking Designer SE/LE. I quilt smaller quilts on the Designer II.
Dream Machine Husqvarna Viking SE/LE. Love, love, love this machine. Of course I do a lot of embroidery on both the Des. I and the Des SE so I get a lot of use out of all the machines, just depends on what I'm working on at the time. I have a really bad habit of working on two or three projects all at the same time because I don't want to get bored.
