Yes you have serious issues!... I don't see the Atomic Pile mod on your list.

OK,Sidekick74,when you order the Batcave spinner,also order the new "Atomic Pile" Mod also from Yelobird! It's a little pricey,but it makes the game,literally!!I don't use Pinstadium lites,but Pinnovators has a headphone mod that really rocks!!Allows you to control volume and mute from the coin door!! And don't forget the P.D.I.glass

Right,what he said!!!!

Seriously consider a playfield protector also. BM66 is known for deep dimpling. Also leg brace reinforcements for the front cabinet. Some Stern cabs are prone to splitting.

Don't have a BM66 but the crane upgrade kit looks pretty cool as well.

Pinball in general is both an addiction and often a sickness. Staging your awesome game for a make over is not at all an issue. IF however you find yourself buying parts and mods for a game you sold or don't own Then you have a problem! lol I have actually purchased playfields, back glass, even plastic sets for games I didn't own just because I said what if... Thats when you know you've crossed over to addiction. lol Good luck with Batman 66, Truly one of our favorites and understandably why our mod interest is so strong for this title. Just an Amazing game.

I reckon you also need to add:
1) Yelobirds Batman 66 SLE Premium Speaker illumination kit; and
2) Yelobirds Batmobile 66 Custom Eaglemoss/Hot Wheels Universal Plate Kit to have the bat mobile and batboat mounted on....and if you really want to
3) Chrome Candys powder coated lockdown bat emblem and bat selector to replace the stickers.

Way too many good mods for this one
