One of my FMQ feet was really noisy. I couldn't figure out what was wrong. I'd just had the machine serviced and it wasn't noisy with the straight stitch foot on. Turns out the FMQ foot needed oiling. Nice and quiet now.
I only used the walking foot for my 2200 QVP Mini (2010 equivalent) once and wasn't really a fan. I got the machine mostly to FMQ and I think I'll stick with that.
