In my humble oppinion, Black Powder is about like bottled water, everyone has their own brand, and everyone tries to market it as some kind of an exotic gourmet drink of some kind. It's water for crying out loud, H2O, Two Hydrogen atoms attached to one Oxygen atom. It's ridiculous to think that there is a gourmet high end water, alot of marketing hype if you ask me.
Ditto, ditto for Black Powder. BP is a centuries old formula, unchanged in all that time, 75% Saltpeter (Potassium Nitrate), 15% Sulphur, and 10% Charcoal. It is ground down to a very fine powder with a little bit of a binding agent, such as Gum Arabic, or Dextrin in a wet mix process. The wet mix is layed out to dry, the chunks broken up into smaller grains, and sized to various grain sizes by passing through a series of sizing screens. The final step in the process is to tumble the powder with a bit of fine graphite dust, to coat and protect the powder grains.
It's a very simple formula, and a very simple process, although a bit time consuming because of all the milling involved, which is done by automatic machines.
All of the modern manufacturers use nearly the same formula and the same processes. What minor differances may exist, if any, are so minor, in my oppinion, as to be insignificant.
The major brands of BP mostly sold are Goex, Swiss, and German (Shuetzen) powders, I just usually go with Goex, it is the cheapest of the brands at most outfits, and works as well as anyone elses. There are several online distributors for BP, the one I use is The Maine Powder House,

They carry all three of the above powders, with Goex comming in at $15.00 a pound, but, you have to pay for the $20.00 hazmat shipping fee, and for shipping, in orders less than 25lbs, at 25lbs and above, the company pays the shipping and the fee for you.
In small quantities, I would suggest just finding a local dealer who carries Black Powder(s) and just pay a little more for the convieniance of a direct purchase, it really doesn't pay to purchase BP online unless you have no local source at all, or, you are buying in quantity in order to get a price break, and a break on shipping and fees.
