I have an OLD Babylock Protege and one day I was starting to sew on it and the needle broke so I had to unthread the needle at which point the loose part of the needle fell into the interior of the machine and I couldn't see it. Then I got my flashlight and long tweezers, finally found the part of the needle and removed it. Then I had to find my new needle and insert it and rethread the serger. Whew! Since all this had taken me two and a half hours, it was now time for a snack and recuperation time. No sewing that day.
But that being said, I still love the serger for finishing seams and would like to get a new one. This time I would get it where they offer classes so I could use it for more things and maybe quit being afraid of it.
