What is wrong with your sewing machine that would warrant spending $179.00??
If it just needs servicing then that is something you can do yourself. If you have the machine's manual follow the oiling and greasing instructions.
Something similar happened to me with my very first vintage sewing machine. I asked at a local Sew/Vac store how much it would cost to service it and as I remember it was $130.00 plus tax. No way!!! I have since learned to do it myself here on the QB.
