Quoted from DrStarkweather:
I like the flipper mylar protectors from pinballlife. Pretty stealthy and they fit under the button and prevent wear.
DrStark, do you mean these? http://www.pinballlife.com/index.php?p=product&id=1870
Seeing as how Pinball Pal isn't filling orders, how do you think the Pinball Life protectors compare with them?
