Yes, its not realistic, but did you honestly expect it to be? Most people already know that and like me could care less. Its entertainment and its science fiction.
That's when I sold my factory stainless one......the standard ones are going for $1600-1900 right now (in very good condition). The stainless was up to about $2500-3k....I let mine go for $1950. It would only be worth $1000-1300 if they didn't use them in Tombraider.
