Finally got one!
I saw a Featherweight listed in an antique auction about 3 weeks ago. Unfortunately, I wasn't going to be home the day of auction so I decided to take a change and submit a silent bid, sight unseen. When I called in my bid, the auctioneer told me it had the case and looked good. On returning home later that day, I stopped by auction and I had won the machine, at less than I bid! I got it for $175. The machine is in great condition cosmetically and even though I haven't sewn much yet with it, it sews good. Has the original manual and the case is in good condition. Needless to say, I was so excited I got it!! I've been looking for several years.
