I can vouch for Hunny_Lee, as that's the place I got my ZAFT costume from 4 years ago, and judging from the pictures, it looks like it might have even seen some improvements (The backside of mine doesn't come down quite as far as I'd like, although that's probably because I think I wore the belt a little lower than I am suppose to. I need to pull that costume out and use it again sometime, lol).
It is not a darker, burgundy color like you're looking for though. That's the only complaint I have, but the quality is excellent and honestly, color shades aren't always totally consistent in the show anyway, so I don't personally think of it as a very big deal. That's just me though. You even get the underclothes for the sake of accuracy nowadays, and those totally weren't an option back when I got mine.
