Any particular reason for limiting your options to EU-coutries? eBay's always a good place for fishing Hong Kong-releases and other el cheapo-dvds. I can see there's Battleship Potemkin going for a measly $2.86 (buy it now-price) this very moment. Also, there's Murnau's Nosferatu going for $4 and Renoir's Grand Illusion for $2.99, for example.
