Well I'm late to the party, but I'll be bringing a few pins to sell at the show and have a couple others for sale, but they may or may not get dragged to the show. I displayed games last year and kept getting offers so obviously people show up to look and buy.
$1500 Gorgar - great shape. Minor wear on playfield and minor knicks on backglass
$1000 Silverball mania - perfect backglass, cabinet has some paint cleaned off (I'd repaint it if I kept it), playfield pretty nice with just a little wear around horseshoe
$1400 Spy hunter - great shape. no real wear or backglass problems. some cabinet knicks
May or may not come depending how energetic I am...
$1600 Jokerz - was there last year, has some playfield wear up top and some cabinet wear, but overall great shape and full of LEDs.
$700 Dragon - working and looks nice with some wear around pop bumpers, some paint faded from backglass. May get gutted to get my Sinbad project going if I don't take it
$1400 Bally Star Trek - great backglass, ok playfield with some wear and faded cabinet
All of these are 100% working with good rubbers, rebuilt flippers, new bulbs, etc. They are just games I'm clearing out of my collection because I probably won't restore them further and want some room.
Yeah I'd negotiate on price too, but have to start somewhere... I saw some worse examples sell for more last year...
I'd also trade towards a Twilight zone or TZ project...
