You guys are so funny! Thanks for making me laugh. So guess what? I tried the stupid machine again after about a half-hour and now it's working again. But I'm not rescinding my note to Singer... I want them to know this happened, because I'm sure it's going to happen again. It's very, very strange to me that the machine would just stop dead like that.
For those who mentioned it, I am already dealing with Singer "corporate" office in Tennessee, and have been all along. There isn't a Singer dealer or warranty repair facility anywhere near me (the closest warranty center is in Maine). That's why I have to deal with TN.
I never considered using the machine as a trade-in, so thanks for that suggestion. I know we have Janome and Bernina dealers around, but I wonder if they would even take the Singer as a trade.
Anyway, thanks for listening to my frustrations, and I appreciate all the sugestions you offered. I'll be sure to come back and update once I hear from Singer!!
