well, i picked up some babboon and gorillas plastic miniatures from party city (in the party favors) for $.10 each. these little guys are pretty close to 28mm size, though the babboons are the same size as the gorillas.
since i have tons of head and arm bits left over from my warhammer boxes (no legs and only one or two bodies), i figure i can put orc heads on the gorilla bodies and night goblin heads on the baboon bodies, making some generic monsters. depending on how i paint them or carve up / modifiy the heads, they could work for any kind of goblinoids, trolls, or undead.
i also picked up some sculpy -- i'm going to practice making bodies and legs.
i couldn't find warhammer / gw torsos (bodies) anywhere under the blitz options.
