If you check my post on building a Numidian army, you’ll see I’ve gone all Victrix.
These are superb, cheap, and very flexible when it comes to options for heads etc.
However, years ago I also built a Numidian army using Crusader miniatures and Foundry.
But these days metal is a bit pricey.
It’s personal preference matey.
But have a search for my post and take a gander at the pictures.
