I personally chose Monster (although I still heart Jolt Cola, and still get the 24oz battery cans from Sheetz), as I got a case of 16oz cans for around $26 at Sam's Club.
The one near us has Lo-Carb, Original, and half-cases of triple-samplers of the coffee flavored ones, which are really good, for $20.
Monster personally doesn't give me a crash, it just kinda fades, which is awesome as Jolt always gave a crash.
You may be able to get M-80 or Assault nearby, those have real juice in them, but I personally think they're nasty.
Sam's Club's website also lets you check any store nearby for stock.
Additionally, as I mentioned, you could try Jolt. Sheetz here HAD 24oz cans for $1.87 (included tax), but they disappeared, and now they're $2.29, which isn't a bad deal. Jolt, however, is much sweeter, but tastes alot more like soda. Probably why it has a crash. I know almost every Walgreens also sells them but for abnormally high prices.
Good luck on your hunt for the cheapass' choice of energy drinks
Oh, edit: I remember hearing that some guy drank around...4-6? red bulls a day...died of a heart attack. Meh. That's definately asking for trouble, what people are doing here with energy drinks may not be "healthy" per-se, but it gets the job done, and more than the recommended amount should never be taken. I personally see them as "All-nighters", and not much else, as I drink soda regularly.
