Were I interested and since it's OBO, if the ad is still up in 2-3 days I would write them and say if no one has made an offer, I'd give them $25 for it and offer to pick it up that day (or whenever is convenient for them). This looks like a seller that wants to be rid of the machine.
This machine came in at least two versions. I have both examples, one that's identical to the CL listing above and this one:

The differences are subtle but interesting such as the brand badge and the 3 vs. 2 feed dog buttons. These are nice machines, very smooth. I love the styling: fins, the big 'M' knob, chrome hand wheel, the windowed length dial, and the smokestack buttonhole button on top.
