For me I wanted it to be clean and make sure that it works. Also, they came with a lot of attachments, so you want them and bobbins! For some reason people lost the bobbin case - so look to make sure it has one that fits. (I understand there are some reproductions bobbin cases that don't work so well.) Most people are asking top dollars for them so you want it to be in good condition. I got mine to use so I wanted to make sure it worked.
