Thank you all, I drove out to test it and the woman selling it would not let me look at the bobbin when it was making clunking noises and laying down a nest of top thread on back of sandwich. Needless to say, I was disappointed but she did save me money because I think I would have wanted it if I had enjoyed the experience.
I think I am back to quilting on my DSM which I do enjoy but wish I had more space. Sigh!
