The 66 is an "off the shelf" tank, they have a warehouse full of them, I saw 120g's there too. I think they do customs, but it takes a while, seemed more like an import operation to me. I got a crazy good deal on mine, one of their guys quoted me super low on the 66 at RAP. I asked if they would still honor that pricing and they said yes, so I went and snagged it up!
