Red Box makes plastic 1/72 scale Amazons:
- Amazons (more 'historical', if possible)
- Mounted Amazons (more 'historical', if possible)
- Modern Amazons Set 1 (less historical, more fantasy)
- Modern Mounted Amazons (less historical, more fantasy)
The Modern Amazons come with some purely fantasy mounts, and perhaps their armor is more modernish, but nothing Sci-Fi, IMO.
Catalog of Alliance miniatures, at Red Box. They have an impressive line of Alliance figures, albeit most are pure fantasy.
You can find the manufacturer on e-Bay: they typically sell most of their figure sets at the lowest available price, direct from Ukraine -- far less money than everyone else! I find their quality good, the injection molded details better than you would expect! They paint up nicely, for me, but I am an Army Painter. ;-) Cheers!
