not sure on the weight compared to a co2 tank but the 72 cu in weighs about 4 lbs whil the 48 weighs 3 lbs. the smaller carbon fibers weigh around 2 and the larger ones are around 3 lbs. there is nothing wrong with a steel tank. it is just a heavier and cheaper alternative to the lighter, high priced carbon fiber tanks.

generally the rule of thumb with hpa tanks is that if it holds 3000 psi you multiply the size (in cubic inches) by 10 to get the average amount of shots you will get on a full fill and with 4500 psi tanks you multiply the size by 15. for example, a 48/3000 tank will get about 480 shots on average, although i have heard of people getting close to 750 shots out of them by using upgraded spyders that they turned into low pressure (they operated on as low as 200 psi to fire instead of the stock 800 a spyder usually gets.)

By all means you can stay with C02. There is nothing wrong with it. HPA gives you a few benefits though.

* All weather play. Since HPA is already a gas it does not need to expand in the tank to give you your air. So you can use it in any weather (Cold/Hot) with out fluctuation. C02 needs to expand and as you shoot faster or in cooler weather you will be getting liquid C02 out of the tank. That is bad for consistency, bad on o-rings and the internals of the marker, but not detrimental.

* HPA is regulated on the tank. So your pressure to the marker will always be the same. That means closer FPS ranges and accuracy. C02 is not regulated so as the tank temperature and levels change so does the PSI. Not by leaps and bounds but enough to notice.

Also look in the BST for used, still in Hydro (HPA Tanks larger than 2" in diameter need to be tested every 3-5 years to make sure they are still sound, it is called Hydro testing. So a tank still in Hydro is one that does not need to be re-tested yet.) HPA tanks. You can get them fairly cheap.
