I found my almost-like-new Safe Cracker prototype for 6k. I was pretty happy with that. Also, for as much as I play it and enjoy it, X-Files at $1600 seems a bargain.
Wish I had a better story. I have an almost score. Before I started collecting, I was at an estate sale. There was a Comet, that I plugged in and GI came on, but no attract mode. At that time I didn't even know how to look in the head or lower it for that matter, so I just wondered about it. Someone else came along, offered $100 and got it. I helped him load it up. Ha. Maybe we need a the-one-that-got-away thread too.
