I use a nitrogen tank. It's a little smaller than the typical compressed air tank. I doubt mine is more than two feet tall. I will warn that getting all the appropriate pieces to get it to connect to the air platform(mine was made by Herzan) took some research, but in the end it was worth it. You may also blow through a tank learning how to set everything up correctly, but once you get past the learning curve it is imo the ideal solution.
The last time I had to refill the tank was nearly 2 years ago. The cost to fill it with N2 was ~$40 or so. The regulator and "pieces" weren't cheap but I don't remember how much. I feel like it may have been a couple hundred bucks to get everything I needed, but since then it has required nothing from me.
Everyone's environment is different though and if there were children/pets running about or I had to put it in a high traffic area of the house I think it would be unwise.
