Ok - I just spent the weekend at a fabulous quilt retreat and several ladies had Singer featherweight machines. I am curious about these machines and would like to think about purchasing one to take to future retreats. I currently have a viking D1 and it's rather large and bulky to haul and would like to have something for just straight stitching. Can you please send me any good advice on how to find a good featherweight for purchase? I have looked on ebay and it's a little overwhelming. They had told me that the best is a black and I believe the number was 221, but let me know if you have a different opinion. thanks so much.
