I'll price these for you. Prices added below, IMHO, average working nice games. Granted if you can find cheaper, great, all depends on seller and condition. Good luck.
Try Pinball Warehouse, Pinball Plus, Nabours Novelty, and of course craigslist.
There is a nice Dr Who for sale by a friend of mine in Buffalo.
Quoted from jonogo:I'd like to keep it under $1,000 USD unless its something that I really like and/or want. I am looking for anything 1980-2000 with a decent amount of re-playability.
Examples of games that I would consider:
WHO dunnit? $1500
Police Force $1200
Star Trek: The Next Generation $2400
Haunted House $1500
Comet $1000
Cyclone $1400
Taxi $1400
SlugFest $1200
I realize that some of these are going to reasonably be more than $1,000 and that is why I said "unless its something that I really like and/or want".
I am willing to drive to come get it, this of course depends on a comparison of mileage vs desire.. ie I'll drive farther for something I REALLY want.
Thanks for looking! Send me a Pinsidemail with what you have, where you are, and what you want and hopefully we can strike a deal!
