OnebyOne, I’m not convinced there are extra feet. I just unpacked mine. It does have a very beefy guide that clamps onto the walking foot, rather than the hockey stick type. The compensating foot I already had (maybe bought it for the 2010?) and it doesn’t have that 1/4” standard foot that came with mine. There’s the foot pedal stopper, but that’s not expensive.
I only bought mine because I need a second one.
hugs, charlotte
