can't remember the model I used to have, 630? 830? sorry, but I traded it in (at Sew Rite Sewing Machine, no affiliation, just so happy with them) about 6 years ago and he gave me $650. My mom, who'd bought it 23 years earlier said that is what she had paid for it! And I NEVER had an unhappy moment with her, just was ready to buy myself a gift (present for finishing my doctorate)
