Aqualung should still make it since it is currently still used by the military at their dive schools. Although, they might not sell it anymore to the public, just to military contracts. I had a bunch I got surplus a while ago and was selling them on here so you can still find them occasionally on sites like this or ebay. I'd sell you one but I no longer have any more. The downside of it, like people said is that is not a isolation valve, and it has the Reserve (J) mechanism. Additionally, they are designed for a AL80 when it comes to spacing. If you want to use tanks that are a different size/capacity, you will have a hard time getting bands that will fit. In fact, tanks larger than a AL80 might be too wide and not fit at all. You could get one on, but not two.
