Singer Sewing Machine Model 8212C

This is a white Singer 8212C sewing machine. It comes with a foot pedal. I was cleaning it and something went out of alignment. It needs to be taken in for tuning... $20 to do it. I'm a senior and don't have the strength to take it myself. That's why I'm selling it so cheap. Besides, I don't have the tools to even say I can fix it! Motor works, pedal works, light works...but when I put the needle it stops.
