In a pinch, Necromunda figs work just fine. Me and all my friends are wargamers enough to the point that one of us will have something that looks cool for what we're wanting a figurine for -- between lots of cheaply-purchased commons from various collectible miniature ranges (D&D, Star Wars, Heroclix, are great to buy for silly low prices), and our assortment of actual wargames...we're like iPad.
"There's an app (err, mini) for that."
