I have an unscripted terran marine avatar for sale for the price of 150 lindens. It comes in 3 different versions: no helmet, helmet with visor up and helmet with visor down. It also includes eyes, skin, shape, pants, shirt and bald head. It you're interested in buying this avatar then IM me and suggest a time of transaction. I'm usually online between midnight and noon according to second lifes time zone.
UPDATE: I added shoes to the suit and it's now complete as far as I know.
