Howdy, northern neighbor. While I have been to Orcas Island it was many years ago when I was still a girl... so many years ago.
I am "near Seattle" that is specifically Renton, very near the Seahawks Facility.
Those 301s are lovely machines, they were sort of overlooked for many years due to the popularity of the Featherweight, but their value is going up. I have one, it is my only Singer and I just had it out and working the other day when I had someone come by for some sewing help. Last year it spent some time at my neighbor's making masks.
Many of us here are fans of vintage machines. The biggest thing you need for quilting is a good steady straight stitch. Sure... we see those shows and things and machines that can send us text messages and it is so cool what some machines can do... but all you really need, especially to start, is a good steady straight stitch.
And maybe some company -- which you have both at home and now on the boards
