I have had a Singer, but spent more time adjusting the tension than serging. Then purchased the Babylock, Not the most expensive but the one below it (Enlighten). It has the "Puff" Threader for the Upper and Lower Looper. I only need to change dials (numbers on each one) and always have the same look no matter when I get back to serging. If you go to the most expensive one It has a place for serging with 8 cones. (Which allows you to do the hemming on knit fabric (the double roll of stitching) I just sit down to the serger and start stitching and am very pleased with it.
