Well this is just a shot in the dark, but if they are not dinged up I would ask $350.00 and maybe settle for $300.00 plus shipping. Of coarse then there is the boxing up.
If they have dings that can be seen I would be between $225.00 to $275.00 plus shipping.
They are getting hard to find.
I would probably make a deal if it was someone on this site.
