I like the Singer 201 or the Singer 15-91. I own many of the others you mentioned. The 99 is a cute 3/4 machine. I do not care for the 66 and would take a 15-91. It works different in the bobbin area. The 201 has a larger throat area but smaller bobbin area then the 15-91. The 15-91 is supposed to be more desirable for free motion quilting. I personally prefer the 201 but I do not free motion on it. It is a smooth ride and a nice big machine. We have one on hand crank and one electric one.By the way I also have a Janome 6500, beige 301 and a 401. I do not notice that you have a Feather Weight. I like those too and my favorite one is the white one. It is even smaller and lighter then the black one.
