Here in the Midwest its an extremely fickle market. I have seen new ones in crate sell for $500. I have seen used ones advertised for $3000 and sold, but I don't for how much. Last I knew a new one could be purchased for around $2600.
If its all there, unused and not rusted up AND you want a Listeroid probably $1500 max give or take? If you looking for a bargain to flip quickly then $600- 750 and expect a long wait for a buyer at $1000, interest in Listeroids is very small group of people.
