The mechanicals and electricals are no big deal. Just judging by what I've seen at thrifts, it seems a lot of machines are sent packing just because the foot pedal or wiring needs a little work. The machine itself is usually great just needs a good cleaning and oiling.
Thanks for the link. I've never been inside one of those type of speed controllers. All of the ones I have taken apart have been the ceramic block with the nichrome "springs" wound around and multiple contacts. It will be interesting to see which type it comes with.
If the speed controller is too bad, I might just try one of those fancy newfangled electronic speed controller pedals. I've read that they give much better control and it's a more stable speed too. They are only around $20 so I won't spend a lot of time on the pedal especially since it and the motor are replacements, not original singer.
It's 7:54 pm here and Fedex still says delivery before end of day today on their website. So, I'm sitting around waiting, hoping I don't have to wait until Monday.
