I really hate running out of oxygen, almost as much as dealing with those awful tanks, so I use a liquid tank. They're actually more economical if you're blowing every day. The same amount of oxy that is in 16 K tanks costs $80-120, plus $60 a mo. rental. Hard to beat $10 a K tank!
A Knight Bullet is a two stage, like a CC or Barracuda, right? That's pretty hefty. If you were torching 5-8 a day liquid would be worth it, but I guess not 5-8 a week... I'd probably go for an oxy concentrator/generator. Personally, I've wasted a lot of time and money by not investing in one of those.
