This new one replaced the wonderful Singer I picked up at an estate sale -- sadly lost in the flood of Hurricane Sandy. But when I got it and opened the manual my head immediately started to hurt. Our son was the serger king and did all the threading and adjustments. So, I found this one online at Walmart. Sadly since we lost the house, our son is no longer living with us, but he did come over to help the other day. I read the manual and said to myself, "Self, you can do this." I was wrong. Hubby got it going. Two needles are confusing, but I'll get the hang of it one of these days. Yes, the Babylock self-threading was tempting. The price was not.
