I have had a tank of CO2 I have used for quite a while.  I have seen the expensive systems too.. Like the PowerTank:

http://www.powertank.com/  (you GOTTA see the video on the home page of the huge tire beeing filled, then you will know what I mean about these systems!)

$400-$600 bux!!!

 or the more economical Outback air:

SO, I decided to freshen up my tank system:

I bought a regulator from Outback air for  $55.00
a SUPER SUPER nice Milton Air Chuck/Gauge Ebay  $20.00
and a very nice Poly coiled hose, just like Outback has for $11.00 plus shipping

I had the tank, so that was free.. and ended up with a "PowerTank" for under $90.00..

While I was at it, I scrounged around for gauges and an old oxygen regulator, and came of with the steel tanked unit for FREE!!!

Now I have one for the Tracker, and one for the tow rig/ATV's... and I can use these to fill my Instant Air (Like PowerTanks minis, they sellem for $190) for the quads themselves...

Who needs a friggen compressor... these tanks blow onboard air AWAY!!

Checkem out, the blue hose is the nice one.. the other is for my tow rig.

my dad has one in his lifted rover

I work with a guy that scuba dives.  I keep dropping hints to him that if he ever wants to get rid of his old tanks...

those work pretty good too!  They don't have the capacity of CO2, as Carbon Dioxide is a liquid at that pressure and temp, but AIR is better in that it's drier, and is just air, after all..

Does anyone know how much it costs to fill a 2216psi Scuba tanks?  how about a 4500?

I think I would rather run air, it's just hard to find around here... not too many places to scuba here in Ohio.. lol..

Here are my lastest and probably final additions.

I found a guy here in Cincy with GREAT prices on tanks.

He sold me a nice, blasted, freshly painted aluminum 10 pound tank, with a new valve and new certification, FILLED, for $55.00.. killer.

While I was there, I went ahead and bought a 50 pound tank!  Most places lease you the tanks, like $100 a year, or something like that.. He blasted and painted one for me, installed a siphon, so I can fill other tanks with it, and installed a new valve, AND filled it with 50 lbs of CO2.. for... $107!!!

I can fill the neighbor kids (and my boy's of course) Paintball tanks, I can fill my 10 pounder, and I guess even my 20 pounders if I want.  They also quoted me $20 to fill the 50... yeah.. that's about fifty cents to fill my instant air, or a Paintball tank.. yeehaw... I'll charge the neighbors $3.00 to fill thier tanks, fill about 10 to get all my money on a fill, including gas to get there and back..

Yeah, I'd say my CO2 needs are now filled.. 

The 10 pounder is for my Tracker, the Instant air for the ATVs and around the house. One of my 20 pounders for my tow rig, a 20 pound back up, and the 50 to fill them all.

 

If you are wondering how many times you can air up a tire with a power tank..

In my case, with my small tank, at my pressures (5-20)  I get more than 40 fills, OR 10 air ups..  Less if I use the air.. but still.. that's a LOT of air for $4.00  (My cost to fill a 10#)
