I was just given this machine today by my old room mate and it says right on the box SQ-9000 I havent opened the box yet but I have heard good things about Brother. I'm just so happy to have a machine that works, I have had my old singer for years and years and I have 2 black cast iron, treadle machines in the garage, I love to sew but havent had a working machine for soooooo long, think I will be locked in my room for months sewing like crazy with all my own disigns and ideals. I was looking for this machine on line and this is all I found on it was your question about it. So let me know how it works if you bought it. Thanks......
