Do not fear you have to sell either. I have 4 and they all work. The one in the back closet does not work so it does not count. My Gd comes over we set up 2 of them and we make quilts, curtains, pillows and special gifts. My GS has used one of them. No, I do not sell any machines. Enjoy them. Wish I lived close enough to go shopping with you. Sounds like a day of dreams come true. Helen
