Just joined the club a few weeks ago and wanted to upgrade the incandescents to LED. I know how badly these flicker, so I got a Comet kit with bulbs and an LED OCD board. I spent the afternoon putting the color matched insert LEDs in and was just watching the machine and seeing how great the LEDs look. I brushed up against the flipper button and suddenly I hear Homer say, "Oooh! Look at all the pretty lights!" I gotta say I love this game already...
