Mixable pre-workout drinks can save you a lot of money, but I have not tried the universal one yet(or any of them actually, but a guy at the gym likes some fizz stuff...I think twinlab makes it). I have the universal BCAA stack my friend gave me cause it was too sweet and didnt mix right, but I actually really like it. The rage stuff is cheap so I would say to just give it a shot and if you hate it, find a friend to buy the rest of it or something.
