I've just recently heard about the headwaters, but they look just like the Marathons do. From what i gather it is a guy that used to work at Marathon that started it. Dunno though.
When I ordered mine, I spoke with Paul and he did used to work at Marathon. He tried to buy the company and they wouldnt sale it to him so he left and started HeadWaters. Small business that he runs along with his wife for the most part.
