I have a Babylock but I bought mine 14 years ago. I bought it because we bought a "new to us" house that had no window coverings and lots and lots of windows. I didn't use it much after that until the past several years. I love it for making clothing and finishing seams. Have seen some pictures of quilts using the sergers, but have yet to try it. Would suggest differential feed, 3 or 4 thread options and ease of threading. The lower looper can be a real challenge sometimes! And free-arm - I use it often for hemming pants and shorts of putting in sleeves.
