I would go for used headlights that have had the plastic adjusters changed and are working fine but the likely hood of finding any are slim to none, Not bothered about the lens so much i can clean that up no problem.
My lights are fine and level not too high / not too low but the adjusters are broken at the very least, I get a headlight range message each time the ignition is on needing to press the button on the radio to get rid of it, Have been meaning to sort this for awhile and its possible if the MOT sees the message they will fail unless the key is left in once switched off and the message doesn't come on till the key is removed an re-inserted. But i'd like to if possible to fix the issue but i don't feel comfortable changing the adjusters myself and even then i'm not sure what else is wrong as i'm sure i can only hear a motor moving on the drivers side.
