Here's the thing... I love hunting for games, negotiating a deal and making a road trip to pick up a new game. I also find auctions to be a rush. But I'm out of room and I love my current collection as is. However, that doesn't stop me from checking Craigslist, Pinside and Mr. Pinball every day.
So I've resolved that my next pin will be a mechanical 1930's game (like Rockola Jigsaw, Genco Official Baseball or Shyvers Cannon Fire) because I know that they're rare and challenging to find. It fills my need to hunt, but I'm far less likely to ever end the search.
