I have 4- 301s. Two always have quilts on them in FMQ progress. I use an all metal foot, I did not like the plastic end ones. I think the visibility and manuverability is better. I just love the quilting on them. The 401 has to raise the needle plate for quilting, and I find it hard to sew with that. I use the 401 for piecing or zigzag. The 301 is easily portable for workshops. I use Isacord thread for quilting- thin and strong.
