Vintage Omega Seamaster De Ville 166.020

Hi, does anybody know where I can find a vintage Omega Seamaster De Ville 166.020 stainless steel with a cream dial? Would look like this: http://www.watch-colle.com/watch/OM/om301a/OM-301A.htm

Would be great if someone can recommend a reputable eBay seller or is looking to get rid of their old Omega. Thanks!
