Finding a good set is like hens teeth. Shabby one's with rusty lights sell for well over £100. I managed to find a brand new set about 18 months ago, after searching high and low for over 6 months, and I got them for £250, which was cheap, as I seen a mint second hand pair sell not long ago, for more than that. A lot of them these days don't have proper lenses in them, they have cheap halfords shite lenses
