I got mine for very cheap, 68/4500 fiber wrapped for $150.
There seems to be a lot of burst disks/nipple o-rings being busted.
I've played with it for a total of 3 times. The third time, the fill nipple o-ring busted. When I went online to check how others are doing with their tanks, they also have the same problems, along with the burst disks. I'm sending it in right now, and thank God AA has great customer service. I'm afraid the rushed into making this product and didn't put their world-famous quality into them.
The big guage also doesn't allow me to fully screw in my tank. I have a mini drop on it, and I can only screw it in so far. The on/off takes card of the rest of the distance. Sometimes, it gets in the way and my wrist is uncomfortable.
I bought this tank for $150. I'd say its a very good buy. But now they've raised up the price to the near $200. There are other tanks out there with the same price such as crossfire tanks. I'd get the crossfire tanks. Overall, they do have great customer service, and they usually have great products, but it seems they didn't clean out all the flukes on this tank before selling it to the public.
