From the two I much prefer the 201.
Like mentioned they, 201 versus 301, are very different machines. I do like the 301 better then the Feather Weight. The 301 is a full size machine. Because it is slant it is harder to find feet like the quarter inch foot but they are out there. I think it is easier to compare those two, 301 versus Feather Weight, as they are both light weight take along machines (portable).
Now the 201 is a beauty but a boat anchor. It sews like a dream and has a super big throat opening. If I had to choose between the two of them, 201 versus 301, and I had a designated space for the machine at home and I would not need to take it places, I would take the 201.
DH and I own 2 Singers 301 and 2 Singers 201, one converted to hand crank.
