I have two, one with all the accessories and book, but without a table/cabinet, and one with the cabinet. I paid $7.50 for each one in places far apart. The great price was because I was in the right place at the right time and was paying attention. Sometimes you pay far more running around trying to get the bargain than you would just paying the asking price. I love the way it sounds when I sew, the look of the stitching, the uncomplicated care of it, the fact that it can sew just about anything without a lot of fussing around. I have yet to try free motion quilting with it, but have read accounts on this board from people who do FMQ with their 301. I have a Singer Featherweight and it sits in it's case while my portable 301 gets taken to working get-togethers. For the last two years I have sewn baby gowns for our White Cross Mission charity on my 301 and love the way I can stitch those narrow little ties so close to the edges. When attempting to sew them on my electronic Pfaff, the narrow ties just don't feed well with the wider feed dogs and foot.
I would quiz the seller about the accessories for the machine and question the fact that it has only one bobbin. It sounds like you are going to get a 301, whether you buy this one or keep looking. If and when you do, don't buy those off the peg packages of bobbins made in China.
