DanDan: As mentioned, $20 each. I really should have said $250 for the whole lot, because let's face it, $200 is getting 6 of em free, but I'll stick to my original price and not play a switcharoo on anyone.
Nocturnal: Most of them are plastic, but the Dark Angels one (the one with the plasma cannon) is a big metal bad boy. All of the optional weapons, of course, are FW, which means resin arms.
and as can be seen, I took a few horrible pictures and threw them in.
