Weirdwolf - around $70 - 80 complete and good condition, without tail & gun around $45 - 50 tops but then its very, very hard to find the tail, the gun not so much.

Siren - without head lasers -$40 - $50, the head lasers are kinda a B%$@h to find though. Wish that darkov guy would make repros , My siren is missing his right head laser
