Powertanks is probably the best on the market and the people I know that bought there systems use Powertanks. They are good but pricey. Like I said earlier poor boys have poor ways. I built mine out of a bottle I found laying in a snow drift. It is whats refered to as a 20 lb bottle. I had our gas supplier at work fill it. Built a bracket to hold it secure but can be unstrapped to carry it where it is needed and bought a fixed regulator from Polly Performance. It was less than 75.00 plus some labor. It gets used every trip out for something and will last over a year.
You could also go the used scuba tank route just have it pressure tested first. You could also have the tank filled with nitrogen instead of CO2 if you have a local supplier.
“Somebody has to speak for these people. Y'all got on this boat for different reasons, but y'all come to the same place. So now I'm asking more of you than I have before. Maybe all. Sure as I know anything, I know this—they will try again. Maybe on another world, maybe on this very ground swept clean. A year from now, ten? They'll swing back to the belief that they can make people...better. And I do not hold to that. So no more runnin'. I aim to misbehave.” Mal Reynolds Serenity/Firefly
