It was my ACDC Pro at the Gold Coast AFL Stadium with thousands of people there, and a line up at each machine on freeplay. It was put on 3 ball games without ball save. I was there for about 14 hrs from memory.
The games didn't last long at all, a minute or two at best n some kids walked away mid game cause they just didnt get it, or couldnt get the
ball to eye co-ordination thing happening. All little kids about 6 to 12 yrs old.
Hence the machine was flat out all day and never got a stop, stayed durable and never played up once.
Re the high priced pins, its just not ebay and dealers who want crazy money, most collectors also want top dollar as well, nature of the game.
