Ken--please help! singer touchtronic 2010?

Hi, Ken....this is sherilyn foley. yu helped me before with my singer touchtronic 2010.....so it's been working great again after I replaced the foot pedal. I was using it yesterday nd a bunch of thread got jammed removed all of that and filled a bobin and now the bobin (or needle--however it works) won't pick up the bobin thread...I too it in to a sewing machine repair man and he said 99% sure it was a broken gear. ...$150 to fix. he said it's not worth it on this machine since it's old. Do you agree. Is there som easy fix or patch or "band-aid" I could put on it to remedy the situation. I hate to buy a new one...i used this one maybe once every couple of months for simple alterations/repairs.....you seem to know everything about sewing machines...any advice would be SOOOO appreciated!

thanks,
sherilyn
