LED, LED-OCD, ColorDMD is all you need. Don't be that guy who zip ties shit all over the place
Sounds like you have just the right amount of mods.
If the game is HUO or super nice, get clear guards around the flipper buttons ASAP. Also, if the paint in the shooter lane is intact, put a little piece of mylar over it. If your center ramp, (the one in the garage) is cracked, and they are often, get the cliffy. If it's not cracked, get the cliffy. If your I&S hole is good, get the clear protector, otherwise, get the cliffy.
I'm sure there is more, if I think of anything else I'll update.
You're lucky, lots of guys here have sentimental attachments to shitty games. You just happen to have a sentimental attachment to the best pinball game ever created.
