Ok - let me put up a disclaimer so no one gets their feelings hurt - I am not judging ANYONE here with what I am about to type.
I do not understand why some people do not just invest in Pingulps. As pinball owners, we pee pee our money away to every single last lil' area of these machines - LEDs, Cliffys, new ramps, plastics, mods that cost hundreds of dollars each - yet we neglect two very vital areas: the manuals and a place for drinks to sit. I have 3 machines - none of which are over $2000, and I flat out made sure I had at least 1 pingulp ready to go. For anyone to have a restored TAF to play with no Pingulp on it = like a car without a seatbelt installed for the driver.
For that drink to have spilled on TAF is a suck situation, but there is NO, zero, zilch, not one reason why a drink should go on top of a pinball's playfield glass. That drink could have gone on the floor, and this would have never happened.
I just looked at the OP's collection - that is nearly a SOLID line of all A titles. 10 machines at $11 each = at most $125 with shipping for 10 Pingulps to be completely and totaly safe 1 for each machine - 2.5% of what a $5000 TAF would cost - and that's one of the ten titles listed. Bottom line: get the Pingulps.
