HPA stands for high pressure air. N2 is nitrogen but when people say nitro/n2 they usaully just mean HPA because nitrogen was its predecessor. Both HPA and nitrogen are high-end gasses and most HPA tanks/guns can use nitrogen as well. But it doesn't really matter because nitrogen is very rare since HPA is easier/cheaper for a field owner.

CO2 is what most players use. It has more impurities then air. since co2 can be stored in its liquid form in the tank more easily it hurts o-rings. This means co2 can not be used on higher end guns with lots of o-rings(electro-pnuematic guns). However, if you get your co2 tank anti-siphoned it will work better on one of these guns. However, since you can get a used steel HPA tank for around $30 or a new one for $60 this would probably be a much better option then getting your tank anti-siphoned (since the co2 tank is $20 and an anti-siphoned set up is another $20)

In terms of how much a HPA tank costs it ranges from $60 to $300+
Steel tanks range from $60 to $80 depending on size and brand. Most are 48 cubic inches and all can hold capacities up to 3000psi. Fiber wrapped tanks are lighter and can hold higher pressures. They also come is more sizes and shapes. The only ones i would recomend is a 45 cubic inch or a 68 cubic inch. a 30/68(3000 psi, 68 cubic inch) tank would be around $180. A 45/45 or 68/45 would be around $200. Some fiber-wrapped tanks have low-pressure outputs. Do not buy one. These are only for guns with poor quality in line regulators(like BKOs or various angels). Wraths should be fine with a high output pressure tank. Adjustable tanks vary in price but i would not suggest one since a preset one is fine/better and much less expensive.

Brands i would recomend are:
Pure energy, Crossfire, and Macdev.

edit: dont but dirrectly from macdev because they are located in australia.

edit2: to answer the original question: as long as you dont want some tac-sim type of marker get the wrath as its performance is better then the cockers in pretty much every possible way.
