It’s only $85 AUD and about ~1 hour trip to go pick it up if I decide to get it but I wanted some outside opinions. I sew a lot but not a lot of heavy duty type fabrics and I suppose I don’t really need a zig zag stitch (I heard older machines generally only do straight stitch) but how is this model in the way of easy-to-locate accessories, how is it to use, will it be a hassle to have serviced, etc.?
Anyone own this sewing machine? Opinions on it? Thanks 🙂
