Just wondering what some of you Marshal's out there charge a Mad Scientist when he wants to invent a gizmo out of the book? A gatling pistol runs $800, or a grand depending on where your looking...now, when a pc makes one he's not likely to have anywhere near that 19 reliability...so how much do you think is fair, 1/2, 1/4 of the price? Does it say somewhere that I missed?? Thanks for your input.
