I've been lusting after an old 1940s singer for years. I've yet to hear of anyone disputing that their stitch quality is better than even the very best top end modern computerised machines.
It'd be nice to own a piece of history too. Not to mention, the older ones are gorgeous.
@Reynard Listening to you I don't need a new machine at all!
I've also got a 1904ish Frister & Rossman, but I've never even tried threading that. It's just a pretty ornament - £2 from a market; not as much of a bargain as your Singer
Daughter has basic singer and it's started to struggle to sew two thickness of cotton without snapping the thread.
