I wouldn't use a FW for FMQ, but that's just me. I use my 301 with a darning/FM foot. For SITD, I use the same machine with the feed dogs up and the tension backed off a bit if it's a thick quilt. I love the SITD foot from april1930shoppe. For me, this machine doens't need a walking foot. I haven't had one pucker, front or back, but I think that's more of a sandwiching issue than a quilting issue.
