The Duet line of machines are the exact same machine as the HE machines
at Sears, except with different styling and different functionality of
the controls. Duet machines actually have more trim, so repairs can be
slightly more difficult.
I don't know if there is a Duet equivalent to the HE2, but these are
the machines that seem to be a bit more problematic. The Duets that
are equivalent to HE3 and above are the ones you want.
