I've ordered ballast from Arizona Rock & Mineral before, as some of you have as well, and I'm also on their e-mail list. Just today, I got this email from "Champion Express Ballast," and I was thinking, "Wow, that's pretty sneaky, the Internet knows I've bought ARM Ballast before and now they're pushing a competitor's product to me..." But at the footer of the Champion Express Ballast email (which doesn't show that much), it says "ARM Ballast" and gives the same company's address. Champion Express Ballast has a website: http://championexpressballast.com/ and not really much in there. They only sell "Salt and Pepper" mixed ballast and generic "Ballast" in N, HO, O and G scales. Does anyone know what this is about? Is this a subsidiary product? Is this ARM's "beginner" product line?
