I have always said"my Sandman is only worth what someone is willing to pay for it". If that is what I want for it, then I will be happy if that time ever comes. People have told me I paid to much for it but I was happy to pay what he wanted. I love my girl and have been happy to spend what it has cost to restore, to the fact the second one will be started next year. If you want to pay 50+k then go for it. No one can tell you how much you will need to spend. I could have bought a Sandman fully restored for about the same price as my has cost, but the one I have I enjoy so much knowing I did it. Just my opinion!
