2 the system comes with a small air compressor that pressurizes the air tank. You can go up and down as many time as you like.
This is not like a propane tank that comes pressurized. The kit comes with its own compressor which charges the air tanks.
If the tank repressurizes, what is the advantage of having a 3 gallon tank as opposed to a 2 gallon tank?
Also, you mentioned that $3,000 is the NSXPRIME member price. But on your website, it looks like $3,000 is the price for anyone. Is there a special price for NSXPRIME members?
