I resisted the mania for a long time... until I found one that was for sale for cheap. I can use it if I want to, but i just love looking at it. I'm currently using it as a bookend for my little bolts of quilting fabrics that are stacked in my quilting bookcase like books.
There's no way I'd spend $400 for one. Not when there were millions of them made and still in circulation.
There are MANY cool old sewing machine models you can love and enjoy using, and most are very cheap compared to a featherweight.
