Agree 100% with Joe on all counts.
I started collecting vintage machines but limited myself to treadles because I didn't think I could do electric work. I've finished two now, and working on my third.
There are lots of tutorials and video's out there to help you along.
If you or someone in your family can handle a screw driver and follow instructions ... the machine can be repaired. It's not rocket science.
If you're not up to the task, there is sure to be someone local that is experienced with vintage machines.
I found this guy just by searching "vintage sewing machine repair Herndon VA". I cannot give a personal testimonial, but reading the website ... looks like he knows his way around a vintage machine and CARES.
