Hi, I am a newbie to collecting vintage sewing machines. Family thinks I lost my mind, but, I think the older machines are so much better than all the new ones. Don't get me wrong, I do have some that have all the bells and whistles, but, I still like the old ones. I have a Singer 401 and Singer 503A. They are both in cabinets. I would love to get a treadle machine. Today, we are supposed to go to some antique stores and maybe some thrift stores. I do have a question. What machines should I steer clear of? You see, I started to read this thread, I'm not very far in it yet, so, was wondering if there are some machines that are hard to get parts or needles for, or if the parts and needles are very pricey. Any help will be greatly appreciated. Thank you. Laura
