I think you should get the grates replaced, line the firepot, replace the windows, clean the stove up and install her in your home.
Once that is done and you see the money you save you will then wonder why you ever even considered selling this jewel of a stove!

The money you will save every year will be more than a one time payday you would get selling the stove. Plus you get to hang out on this great forum and discuss your new addiction.... COAL!
