Hi All! I am interested in getting a older singer sewing machine. I am not really interested in getting a FW. I was wondering about the other older models, for example which one has the most throat space and what attachments are available for which ones? I basically want to get it to try to learn my FMQ as my brother machine (inexpensive model) seems to bounce around and have trouble with bulk. What type of feet were made for these machines or have been made to fit these machines to use for FMQ , Has a walking foot been made that will fit them for straight line quilting? There seem to be a number of different models available on craigslist most of the time...but how to know which one would be best. What would any of you who have a vintage machine recommend and why? Thanks for your input.
