I have a Viking and a Pfaff. I use the Pfaff more as it is easier to thread. I am looking in getting the Babylock and will trade the Viking in when I do it. Then my Pfaff will be my back up. I've been in serger retreats where they have the Babylocks and they are dream machines. They can be threaded in any order, unlike my other machines which have to be threaded in a certian order. They also have many different feet.
