Mine was the day i picked up my holy grail pin, 1979 Bally Kiss.

I had been wanting one for over 20 yrs so when one came up near my home town i grabbed it, even though it was a mess and had to pay $3k to get it.

Best part of all is that it is the very same one i used to play in the amusement arcade in Laurieton where i bought it, and it now has pride of place in my lounge room
