When I went to get my sewing machine tuned, I found that everyone is charging $99 for a tune up! I was a little shocked, but happy to find the Sewing Room was only $75. (and they also have a $10 off coupon you can use to make it $65)
They tuned my sewing machine back into tip top shape (and it was having plenty of problems with my feed dogs, extra noise, my bobbin holder...) It is now sewing like a charm, after 2.5 days. (they said it would take a week, but surprised me with a call yesterday.) They were nice, taught me a few new things about my machine and were overall quite helpful.
