I have already posted a topic at Cemetech that helped me get my head around the pros and cons between the 84+CSE, and the Casio Prizm. However, my third option, the Nspire CX CAS, isn't an accepted calculator among the members of that community. Which one, the Prizm or CX CAS, to a programmer new to C, math student in Alg 2 and Pre-Calc, and a teenage calculator game enthusiast, would you guys suggest? Expert and experienced feedback appreciated!
