Depends on what you want from it. The dials and things cost extra, steel tanks are cheaper, but are heavier and only come in 3000psi, smaller tanks are cheaper but naturally they don't hold as much air. I paid $240 (us) for an 88ci 4500psi crossfire tank, but you can get them much cheaper. If you play front, I'd recommend a 45ci, 4500psi. A front player on my team uses it and he's as mobile as a monkey, I myself am a back player, so I like the big tank for long games and to get the sight point in my marker further from my eyes so I can get a little more precision. But like any other piece of paintball equipment, use what fits you, borrow someones tank thats really big, borrow a small one, and find something in the middle that suits you.
