I'm looking for the 50th Anniversary Gold Train Set. Does anyone know where I would be able to purchase one of these? I've tried looking on Ebay but can't find any available. I've been looking to purchase a Disney train for years, and this year with my dad passing, I am making it a priority to get one. Any good suggestions other than the 50th anniversary set that you can recommend? I'm looking to put it around my christmas tree. Thanks!
