I bought a 758 in a cabinet when I decided I wanted to make a quilt. I didn't want to use my 778, as it was so heavy and also a "portable", so I would have to take it off the dining room table every day. I figured I'd never get a quilt made if I had to do that. It had been so long since I sewed anything, I had forgotten about the tension problems on the 778. The 758 had them as well. I would not recommend them to anyone unless they were in good working order and under $25.00. Of course, some people will put out the bucks to fix the gears. They like them that much. I don't get it, but to each his own.
