I'd argue that sewing machines are among the most complex, high skill items found in a typical home, above the laptop and car. I find it very hard to keep mine operational. I struggle with it a lot more than I sew with it. They require fine motor skills and scads of parts and supplies. If you plan to rent them, plan for a repair staff or frequent replacements.
Compared to a book, a sewing machine is a space ship, and you should see what people can do to a book. To be sustainable it needs a replacement value deposit, which isn't easy for someone who can't afford an entry level model.
