Among my 4 treadle machines, they're all wonderful machines; it depends on what I'm sewing. They are: Pfaff 60,
Singers 201,15-90,237. Only the 237 does zig zag and is the youngest of the group(1965ish).
The electric machines: Berninas 930 and 1031 are my favorites of all; Pfaff 1222E for binding quilts,Husqvarna Viking 875 for machine quilting and everything(when she's behaving),Singers 221(3) and 301 for when I need a machine to take a class that doesn't need a fancy stitch.
