I have a full, never-used CO2 tank for sale for $75. I got it as a spare for my 10lb tank, but I have since installed on-board air, so I don't worry about running out of CO2 anymore.
I paid $100 plus shipping on the empty tank, plus about $25 to fill it. I can bring to Morris Mountain if someone is interested. I can point you to the regulator that I got as well, if you are interested.
