Here's the deal with maille. Virtually all of it is made in India, and is not really accurate to historical maille. There's really nothing we can do about that short of investing countless hours making it ourselves (no thanks, I'd go insane before completing it), or by spending way more money than I can afford to get maille made right.
That being said, allbeststuff, gdfb, icefalcon etc... it's virtually all the same to varying degrees. What we can control on our end in terms of accuracy is the general type of maille we get, be it flat-ring wedge-riveted, or round-ring, pin rivets, or some permutation of the different options out there. So, get as close as you can to what you want, and go in knowing that no matter where you buy your maille from it will require work when you get it.
You will need to tailor the arms, perhaps alter the torso tube, add triangle gores to the sides or front to tailor the waist etc. These things are pretty much a given. So if you go in knowing all that, and you're willing to do what we can on our end to make the best product out of what we have available to us, it really doesn't matter what you buy.
The only caveat to that is, I would stay away from the butted stuff, aluminum stuff, and perhaps even the galvanized stuff (because removing that can be dangerous if you decide to one day).
