Air Tank and MOLLE Pouch

Hey guys,
I held off buying a bigger air tank before because I didn't think we were doing any more scenarios and I didn't think I'd be playing much in college. But after talking to a few cadets and looking at all the upcoming scenarios this obviosuly isn't the case. So does anyone know somebody who's selling a fairly large tank? I mean I can get 1, maybe 2 rounds out of mine right now at the Farm. So anything bigger would be great. And I doubt my backpack will hold up much longer, so if anyone is selling a MOLLE tank attachment or something like that, that'd be awesome. Thanks!

What size tank do you have now?
