For "paracritters" and the like, they sell little plastic animals in bags similar to those green army men. We keep a set in our dice bags to use as miniatures. Make sure to get "jungle animals" or "dinosaurs" -- instead of "farm animals." Goats aren't scary unless they have wired reflexes 3 at least.

But...... there's no pics of fully painted models

(SIDE NOTE: as has been pointed out, the original SR models are realistic 25mm. A company called Ground Zero Games does 25mm realistic scale modern humans, street level figures (suits, hookers, civilians, cops, paramedics, biker chicks etc), and they're cheap as chips at $2.75AUS dollars. And IIRC, they're an american company too, with at least one distributer in Australia. Just another option for those that want the visual 3D aspect to their RPG game.)
