Also when it comes to how accurate you wanna be, consider the practicality of what you're getting or how you mod it. Remember that those suits used in the film were probably worn for a brief scene lasting less time than what we do on an average troop. You obviously don't want to use gaffers tape for your calves for example.
Also despite someone having garrison 'seniority', it doesn't mean he's the ideal person to consult. A lot of newbies are finding that with the more accurate kits out there now, they can exceed someone who got his armor years ago but which is less accurate.
