@John: I hope you get inspired soon to finish yours! My pin is almost entirely in LEDs. A few "normal" lamps because otherwise the playfield get's a little too dark for my taste. I agree that not every pin looks good in LEDs but it works very good for the Scared Stiff I think. My pin was already in LEDs when I bought it so I am not sure which supplier is best. This supplier gets good feedback on the German pinball forum:
