I can bring a very good but not perfect Surf Champ backglass for $150. Colors are excellent. A few minor scuffs, and some cracks in the paint just starting in a few of the letters. Not triple-thicked or coated yet. Pics at this link - https://drive.google.com/folderview?id=17M8g56hNQ3pz6R2irjtuHmjpbFYDKX4Q ... color variation due to some taken with flash, some without. I set it on a blue pad in the pics to help show the flaws so there are no surprises.

In addition to the Surf Champ backglass ($150 obo), I also found a few other random things in my stash I could bring to FPF. See pics at https://drive.google.com/folderview?id=17M8g56hNQ3pz6R2irjtuHmjpbFYDKX4Q

- Big Guns faded translite (I'd acquired a fresher one when I had the game) - make offer
- Big Guns yellowed King's Chamber plastic 31-1006A-557-1 (I'd replaced it with a comparable new piece of acrylic sheet) - make offer
- Coin box with plastic bins but no top, for Bally EMs 1972-1976 (I believe this was from my Sky Kings I used to have) - $25

I enjoy the afterparty because they put the lights lower (more pleasant glow from the machines!) and there is generally little wait for most machines.
I don't enjoy the afterparty because the music is ridiculously loud and generally atrocious (IMO). I bring earplugs, which helps greatly.
