I played some "vintage" 12 strings recently; a Vox teardrop (it was...ok but at $1500 it should have been godlike in perfection) and a Greco (pretty and nice tone but half the pickups didn't work, the neck was warped and the neck was a little too narrow for my pudgy fingers).
I hear that Dean makes one that is moderately ok and dirt cheap but is a little top heavy (but what do you want for $300?). My brother has a Dano that's pretty good and a green Burns that makes me green with envy.
