You can find used choppers for around $400, in better condition.
Not sure about the blades on this one, but try it out and see if there is room to negotiate.
Not sure what that $2000 includes, but seems high
One more thing to look at is the width of the blades that are being sold vs the width of new blades. If they are narrow, there will not be much life life left for resharpening. Those blades look narrow to me.
