I just got one this week from Pinball, Inc.
https://www.pinballinc.com/index.php?route=product/product&product_id=126&search=jokerz
It wasn't the cleanest of molds... gonna take some Novus #2 to it, and then a very quick flame polish after cleaning.
(just got it yesterday... will take pictures of before & after)
But its already wayyy better then the old yellow that's on mine right now.
