Great Purchase!!
September 30, 2014
By clockard from Butler, MO
I was looking to upgrade my sewing machine! I had done my research on line and stopped at an authorized dealer in Rogers, AR. I told the person in the store that I was just ready to look at the sewing machine options I had with Brother, that I had done my online research and was ready to look at the actual sewing machines, but that I was just looking. The salesperson said that was fine and he began to show me the models I was interested in and demonstrated several machines for me. After his demonstrations, I had a good idea of what I was wanting and how much I was wanting to spend. He was so convincing, that I purchased my new machine that day. I love my Brother Simplicity SB3129 and am so glad I went ahead and purchased it. It sews like a dream. I love the bigger table and that it came with all the feet attachments that I will need. Thank you Brother for your great authorized dealer in Rogers, AR.

Great Machine!
August 21, 2014
By Sisterchick from Oklahoma
While I haven't been able to use it as much as I would like, I love this machine. I was sewing with a 50 year old machine, so you can imagine. I love almost every thing about it, although I can think of several little things I would change. I would recommend it to any one.

SB3129 Review
August 14, 2014
By FeatherStitch
This machine has a great LED light. It is fairly hefty, so I assume it is mostly metal inside. It has has a good variety of stitches, an automatic thread cutter and a needle threader. I wanted this machine for piecing quilts, doing thread painting and some general alteration work. It seems to vibrate a little while going full out. I think it is a good value.
