I have various vintage machines including a featherweight and two that can treadle. I have my very first singer I bought myself in 1965 (Aqua 327) which I would never part with. I am thinking my colleagues on the vintage thread will now shun me but my favorite machine of all time is a Brother mechanical XR-52 that is about 13 years old and has given me zero trouble over those years. It is not fussy with thread and will take any fabric I throw at (or under it). I have seen them on eBay and thought about a spare. The original was bought at Costco.
