Glad to see that you held off, and didn't get scammed out of your money..
Or even just had it tied up do to an error / misprint..
Last year when I was pawing around the net for a new airtank,
I found out that several of the nicer ones are made in the same factory..
The precision and quality are there, the fun part is finding them for the best price..
I found a seller on eBay with 9L DOT approved CF tanks for like $460 shipped..
I made sure to order the one that shipped out of the US, and had it in less than 2 days!
They threw in a fitting/gauge, and extra o-rings too.
Same tank as seen selling on Amazon for like 100 bucks less at the time, so I couldn't resist..
The tank is Awesome! Flawless cf weave/wrap, and flawless topcoat.. DOT approved, etc..
Couldn't be happier.
