I just recently bought a Symphony and so far (only had it 2 weeks) I have been happy with it. I have already peiced 2 tops with it and it has been performing well. On my older Kenmore I found I liked using the walking foot for most everything, including piecing. So far I haven't used the walking foot for piecing, but think maybe I will in the future. Haven't yet tried FMQ on it. Have not found any glitches re the screen or speed control.
