Quick update... I got the Cultists done from Mansions of Madness 2nd Edition.
These models felt like super old and crappy sculpts. I'm seriously considering just replacing them with the Reaper Bones Cultist models. They're pretty cheap and realistically, I'd only need a handful. It seems rare to have more than two or three cultists on the board at a time. The Reaper models are also nice because there are two different sculpts. I think they cost about $5 for what is pictured below.
These are the colors I used, in the order I used them. Should be pretty self-explanatory.
