99taws6: The pump can take it to 250 bar, which is higher than a 3k tank will safely take! These are not your normal pumps, they are designed for pre-charge air rifles, which run at 200 bar - it's a lot of work to fill an empty 72/3000, but only cost is food.

My first choice would be HPA, I simply have much better consistance in my shots. But, however, not to dismiss CO2 I do have two 20oz tanks to run with when I'm in a place where there is no other option. Still shoot ok but just a little better with air. Who knows maybe it's just me. When it comes to weight, ehh not an issue since I'm on a remote.

I started out on CO2 (3 -5 $'s a fill depending on where I went) and then I decided to make the switch so I kept watching Ebay for some used HPA tanks..the tanks alone were pricy but I was able to pick up two package deals from ebay (included a marker, an hpa tank, a remote line, and a pod pack - I picked up two of these, 1 with a 98 and 1 with an A5). I was then able to remove the peices from the packages that I wanted (I kept the A5 and both hpa tanks and 1 remote line) and resold the rest and I was able to just about break even on the swap. So if you watch ebay you maybe able to score a used tank as part of a set for a great price and then resell what you don't want/need. The only real investment was the scuba tank (75$ from craigslist and it has a current hydro til 2011) and the yoke (30$ new on ebay) that allows me to fill the HPA tanks. This is great b/c my son and I both play every weekend so we're going through at least 2 tanks a week and when we were on CO2 that was really adding up quickly. but now it doesn't matter how much air we use b/c the fill station is in the back of the Jeep : )

AND I can get my scuba tank filled for 6$ so each bottle is costing us pennies to fill.. a great deal if you can afford the start up cost (in my case it was a little over 100$).

Opps, didn't mean to reply in the middle of your post. See below.

Been on co2 for years. Have two 20 lb bulk tanks that I refill five 20oz, and seven 12ozers from. ( I have 3 markers) But just switched to HPA. I wanted to buy a scuba tank and fill station but was told that I need a "dive certificate" just to buy a scuba tank! That's what they told me at "Sports Chalett" here in Vegas. I could probably find a scuba tank on Craig's list as you did but who/where do you suggest for bulk fills? And for $6 bucks....what a deal!! Actually, I'd gladly pay more, just don't want to hassle a certification course. Been paying $30 for a 20lb co2 refill.
Suggestions are greatly appreciated.
Thanks much
Scoreshot

The local paintball shop here fills my scuba tank for 6$ (it's the same rate whether they're filling a small HPA bottle or a scuba tank (doesn't make sense). I'd also check around for a scuba shop (if there aren't many paintball shops around) most places that will sell you a tank can also fill it for you (assuming it's a real scuba shop and not just a bulk sporting goods store).

Never heard of needing a cert just to purchase the tank - what if it was a gift for somebody? Sure sounds like some sort of scam to me...

Thanks for the reply Phrog,
Ya I thought it was kinda strange needing to be scuba certified just to purchase a bulk tank. It was a sporting goods store here in Vegas. I'll check out some dive shops. Thanks again
best regards, scoreshot

Ive seen on a couple of sites nitro tanks but, of course none of the fields I go to have nitro refills. Is there a difference between nitro tanks and HPA tanks? They seem to have the same ratings to me

CO2, because its the only thing available....and we only have one place to fill that too. I live in a smaller town (25,000) and i'm shocked how little paintball stuff is available to us. I was considering opening my own shop/arena for a long time.
