I have been quilting for 25tears. I currently own a Janome QE. a Bernina QE , a APQS LA. I am trying to decide on a serger. Does anyone have any suggestions? Have looked them up in topics and recieved some help but any more help such as brand name, amount of sewwing heads, self threading and differential feed would be so helpful. At this time Iam in no rush so even a used machine is a possibility. Thank you all for your past help.
