I would pimp it hard with LED's....add target stickers, add the diverter sticker, and if you are so inclined, add the 2 flashers that were deleted in production. If your plastics are nice, you may want to consider plastic protectors. I even picked up the playfield protector for mine. Some dudes have added jet toys to the playfield as well.
I have not installed the diverter sticker yet and may consider not installing it/selling it.
There is a ton of love for F-14 here on the board...Its a great game.
