I would take it to as many different repair people as possible for a "Free" estimate...You should be able to find a expierened 'older' guy that with time can find the part, or maybe has it from another machine. Do not get rid of it, think of all the happy times 'she' has given you. Worse comes to worse, put it on a shelf, a place of honor where you can still enjoy her for what she gave you in many years of service. only then can you buy a replacement. IMHO
