I had the top of the line Viking serger (my 4th over many years) and thought I loved it until I saw the Babylock Evolution! I went home with it from a Nancy Zieman show, and put the Viking on the floor...moved it to a different table, then to the floor of a closet! I use the BL all the time...I do alterations on prom and wedding dresses, sew doll clothes, and even have used it to piece the back of a quilt, which I absolutely loved doing! I am going to set the Viking up as a cover stitch machine, it is too difficult to change back and forth, and the BL's threading is so wonderful....
