Well, I guess that I am not in this league of machine owners....
I have a Kenmore and I just love it. Have been using them for years. I bought this last one almost 3 years ago and have had no bad experiences with it...I take it once a year to get an "overhaul" and she purrs like a kitten.
Don't even need the walking foot for quilting, she just slides right along........
So, I will keep my Kenmore.....she and I make a good couple. MJ
