Update...
Large Marge just came home, with a loud thump at the front door. The UPS guy didn't even bother to ring my bell. I'm happy I was home to get her. I live in a good area but a huge box like that might be too tempting for some.
I got her set up and plugged her in. I don't have time to quilt anything tonight but I did put my foot on the pedal for a few minutes to see that she is much quieter than before. I do hope that this will be my only trip to the machine doctor! She's no longer under labor warranty, just parts, so I'm sure it would cost a small fortune to get her fixed after you add up shipping and time spent repairing her. Hubby said that if she breaks down again, we'll sell her and get something else. I hope this will be the only problem. I am going to work through a bunch of quilts over the next few months to make sure she is good to go. If not, I'll be one very unhappy quilter.
I hope yours gets fixed soon too
I don't know of many people who have had problems with their Lizzies so I'm pretty sure it was just a bad batch of machines.
