This engine came out with a price tag of $79.95.  But it was quickly discounted to $40.

When the Nelson and FORA 15's came out, the value dropped to zero.

Somebody bid $174 for this unit and the owner (maybe never a seller) is still holding out a RESERVE.  We've all got a bin full of these, maybe not unrun, but there's still a lot of Conquests out there for less.
