Sedo have brokered the sale of matrimonio.es ("marriage" in Spanish) for $4,181. Other recent (reported) .es sales include Bioesfera.es ("biosphere" in Spanish) for $953 and hi5.es (hi5.com is a very popular social network site) for $900.

It's nice to see some decent sales since the liberalisation of the .es ccTLD last November (.es is the ccTLD of Spain). I have some .es domains, but not that valuable.
