I have one. I got it as a birthday gift about 4 years ago as I thought I needed one! I have used it when I make pajama bottoms but haven't done anything quilt-wise with it. I do like the idea of serging my fabric before pre-washing. One of those "Why didn't I think of that" moments. However, the threading can be very intimidating. Also, I broke a one of the needles over a year ago and it is yet to be replaced. That should be an indication of how often I use it! It sits on a shelf under my sewing table. Maybe someday it will once again see the light of day!
