Hi Lion,
Nice looking ranch kettle you have there. That's an oldie MBH Mothership that appears to be in pretty nice shape!
Price is for the most part dictated by the overall condition of the grill but location also can make a significant difference when it comes to a Ranch due to logistics and costs involved in shipping. If you can provide more pictures and a rough idea where you are located I'm sure you'll find interest from members who are close to you. The parts of the grill most people will want to see are the underside of the bowl and leg socket areas, as well as a few shots from different angles around the grill and lid. Post up some more pics and I'm sure others will chime in as well.
Good luck with the sale,
Matt
