IQ Gaming has shown us the second Ghost Town spoiler, Technological Exhibition. While the value is a little low for ambitious gadget decks, it can help you build a larger span of gadgets you didn't think possible before.
Perhaps you want a Quaterman to carry a Flame-Thrower. With Mad Science 2, you can build the Quaterman on a 3, but you'll need the Exhibition to build the Flame-Thrower on a 3.
Another aspect of the card is the fact that you can bring a gadget back from the discard pile. Harold Aimslee has been the only previous card that could do such a thing, and he simply costs too much.
The Downside is that you have to run the job with one of the dudes that is integral to your strategy, your mad scientist. However, early game you can use the job at home or on deeds that make it difficult for your opponent to oppose, such as the Maza Gang Hideout. Once you've built up a small army of Quatermen or Wretched, you can Exhibit your wares to the whole town in the square and gain a control point on the gadget. Since the control point is added to the gadget, this could create a few control points on Auto Cattle Feeders at a ranch out of town, making them incredibly difficult for the opposition to oppose.
The card offers discard recursion, cost reduction, skill reduction, and a control point. You're likely to find new combinations of gadgets now that you could invent a Quaterman and still have aces in your deck.
