From a 'hey it's clown puke but doesn't make any damn sense' perspective... Here's a swords of fury I picked up a few months back at a deep discount. All Backbox GI was changed to purple. The camera doesn't do it justice, but it looked ridiculous. They also used all regular LEDs in the inserts. fun times.
Long story - but sadly this is directly from a famous (infamous?) local pinball repair shop like this. On top of the LED job, the drop targets started to go after a week of home play. Still a great deal for the price I got on it, but eesh.
