I have a 401 and I love it. I do not see your photo, so can't comment on it, specifically. Your question is about FMQ and the 401, I assume.
As far as FMQ, (I've not yet learned that skill) the Singer 15-91 is often touted as the best vintage machine for that. The 15-91 is a straight stitch only machine. The 401 has lots of other capabilities, though.
