I love my feather weight, also love my 301, 401 and 500 as well. If I had to pick just one? I can't. DH also got me a 99 on ebay, so after playing with it I might even love it too. Just love them all. Those old vintage singers are really work horses. I really like that the feather weight and 301 are portable. So I guess to answer your question, I prefer any of those old Singers.
