The fluorescent lamp used in that pin is pretty harsh - it reflects down on the playfield and makes it hard to see. I have seen people use a rope light instead & it makes the lighting a bit softer & more even.
I have a Mr & mrs pin, but don't care much for it. I feel that the pac-maze takes away from the flow of a good game of pinball IMHO. I picked mine up for $175 non working & brought it back to life. I have more $$$ into it than it's worth, but it was worth it for the education in repair skills if nothing else.
