I wasn't saying that AL would be a bad choice, but the USD brand is so old that it's not even dive gear any more. They sell snorkeling gear, but I have never seen serious dive gear from them in years.
That is because Aqualung is USD. Same company, Aqualung is the name of the first regulator sold by USD, when Jacques Cousteau passed, the family wanted a name that did not sound like it was an United States Company and yet still reflected his dream. They took the name of the first regulator he made.
At least that is the story given to me by a company rep.
