I sort of hanker after an electric Singer 201k, then I think I have a Handcrank 201k which I hardly ever use, mainly I sew on either Bernina 830 Record or Bernina 1080, both superb machines. The Pfaff 2170 is very useful for the IDT when neccessaryand of course it's embroidery capabilities.
I still have my Brother from 1988 which performs well when asked and, there's a Bernina 1020 awaiting me deciding whether to sell or exchange .. but what would I change it for?
Acquiring more sewing machines is very addictive and sometimes not profitable because we don't use them to their maximum. They are great 'spares just in case', but money sitting there not doing anything and particularly if you have to loan the money even from family.
The Handcrank 201k is for me nowadays very heavy but it stitches beautifully and will definitely come into its own if fuel prices keep rising!!
Look on your local Freecycle group or there is also the Nextdoor group both of which do at times have sewing machines offered for free. You can also put a Wanted request in.
So Bill, think again about the 99k, you will have to spend money for the missing parts, maybe a service but definitely get the motor checked.
