I've always been very, very intrigued by this company. My biggest problem with them is that every forum I search online comes up with the same guy advocating them. I don't think he's affiliated with the company, but he lives close to the company's headquarters so he's gone to listen to their speakers on several occasions. He thinks they're great, but it's hard to find many threads on any forum about them that he hasn't taken the lead in the discussion -- therefore I've always been a little skeptical.
