Recommendations for Vader pieces?

[encased]

Hi,

I'm looking into putting a Vader costume together and am asking for help/opinions on the parts. Currently looking at the suit, leather belts, boxes, armor and what have you.

I haven't decided on which film version so all opinions are welcome as to who has the most accurate of any particular film. And please no arguing, just state what you like about the piece you recommend.

Thanks guys.
