There's a real good Humble Bundle for fantasy minis if you've got a 3D printer
Humble Bundle currently is currently running the "Dungeon Masters Role-playing Essentials" bundle, full of STLs from Hayward Terrain and Warp Miniatures. I've written about it for work here (mostly just waxing lyrical about Warp Miniatures):

The name is kind of misleading, because yes, you can use these for DnD, but there are a lot of miniatures that are really well suited for miniature wargames. Multipart kits for Dwarf miners, Zombies, and pirates; Lizardmen units; pig-faced Orcs; units that are battlefield role equivalents (but aesthetically quite distinct from) the various Chaos daemons.
Here's a direct link to the bundle, with no affiliate code in it:
