I have to say, in my searches in my area (a larger metropolitan area) - I am hard pressed to find these type of machines for less than $100. There are a few listed on ebay, but I am hesitant to do that, because this is my first foray into vintage machines - and I am hoping that I don't have to tackle the rewiring thing right away. And this one comes with a cabinet. I still have not heard from the person who listed it for sale, so I am not sure if it is still available. But it is within an hour - so I can test drive it. I actually love the look of the cabinet. Doesn't match anything in my home, but I like it.
Ann - I was wondering how you found stippling to be on your 15-91? It sounds like you have a Juki too. Have you liked your Juki as well? So many sewing machines, so many decisions!
