grizzlybeast The same text you quoted is mentioned on the HE-350 page which is only a power regenerator. It seems unlikely that an AC power regenerator would have brand restrictions. I take the quote to mean that: A. He recommends you have experience or start off with one of the lower tiered products first (more likely) or B. Requires that you start off with one of the lower tiered products first (less likely) Anyways, just my two cents on the interpretation of the statement. Please let us know what you find out.
