A 68/4500 roughly equals the shot count of a 20 oz co2 tank, though the prices of the 4500's are much higher. But it's a good reference point at the least.
A hydro is hydrostatic testing. Tanks have to be tested every 3 years or every 5 years by DOT federal law. You would have to check your DOT number with the stickys to see if your tank is 3 or 5 year. It's for your safety and the safety of others around you to ensure that your tank is structurally safe, that is what it tests.
As far as the better deal, that's up to you. I would personally save up for a 4500 tank and get a nice tank cover for it. You'll get more shots, it'll be lighter, and more then likely you'll be a lot more happy with it then spending $35-$60 now and then think a few months later about buying a 4500 instead of a 3000. Yes, it's more money at first but much better then dropping some of your money now and then having to save up that much longer.
thanks alot this really helps. I just bought a dp f7 btw but damn, those 4500 psi tanks are expensive. if i bought 1 from the bst threads, would it most likely be empty?
