The best guide to prices is either ebay or the ramsays guide. The former can offer a somewhat distorted view of prices and the latter is about 18 months old since its last update and tends to be a guide price only. The problem with lima is not so much they are out of business but that some of their range has been devalued by the release of newer improved loco's by other makers. The 60 and 31 have really fallen in value since the release of the hornby versions.
