Hi Melissa
The old Necchi are wonderful machines....A friend of mine has one (and she inherited it from her mom (we are both over 50..lol).....
We would both tell you to try to fix it......This machine should run forever...
Even if you decide to get a new one...Don't get rid of the Necchi...wait for the oportunity to fix it....(The right person will fix it)....
Sometimes its just a bit of luck....
