I have a Brother, can't remember the model number and I didn't use it at first but WOW, when i'm string piecing, it's the BOMB. I probably save as much thread as I use piecing. Not to mention having to pick up my snips and trim thread each time I sew a strip. Depending on the size of my blocks, I usually have 5-6 strips on each and that's a lot of snipping & thread waste. I also love the needle down button and the fact you can use it without a foot pedal - just use the start stop button and the setting from very slow to fast.
