Nice thread. I have just started playing in a Deadlands RPG campaign, and I am quite enjoying it. Sadly, we are playing remotely, so no miniatures. But when our Friday night gaming group starts meeting again, I am planning on introducing them to Deadlands, and there will be many, many minis.
Some of the Highgate Miniatures vampires look like they should work well in the old West setting. The bulk of my Western figures are Black Scorpion, and the Highgate minis are a bit small in comparison to them... but the BS figures are on the tall side compared to most old West ranges.
