A decade or so ago, we got rid of a huge collection of about 350 laserdics - a guy drove from two states over to pick them up for his small towns community center where they would play movies for the town.
They always panic slightly thinking we're trying to give it to them (most libraries are inundated with out of date materials people donate), and are happy to give us names and numbers of churches and elderly centers who might take them.
It's not a ton of work and worth it overall.
