the only superpower i want is money ,, because if you have money you can get anything buy anything ,, it's simple look at batman and iron man they dont have superpowers all they have is lot of lot of money ,, plus they are the coolest superheroes ever ,, -_- i am batman 
You can't really buy everything with money; perhaps you could build a suit like iron man's, but at this stage, more than access to resources to build it you need knowledge on how to build a power source powerful enough to allow the whole thing to function and small enough to be mobile.
Maybe throwing a lot of money at it would give you the solution for that in time, but there are other "superpowers" you would probably need ages before acquiring, if ever; to pick on a few from this thread: mind control, teleportation, time travel, mind reading, etc..
