When I was a kid, long, long ago, my neighbor has a FW and I smugly thought to myself, "What a silly, little toy. It bounces all over the table and how can you sew anything bulky (like corduroy bell-bottoms,) with it? I like my 'real' Singer 66. It's a serious machine."
Now that I'm a tad older and a quilter, I do see the positive aspects of a FW and I own 2 of them. First, they're pretty dang cute. Second, they go anywhere and are very light to carry. Third, they are S-I-M-P-L-E! Although, I still think that they bounce all over the table and can't handle heavy fabrics.
Personally, I love the 99 and 99k for a small machine. No, they aren't vertical feed, so they aren't a FMQ candidate, but they're so solid and the stitch just can't be beat. You can also buy about 8 or 9 of them for the price of one 221.
