Since I now have the money, from my birthday and all that, I'm trying to decide which calculator to purchase from a list of five. I've had trouble deciding myself, so I'm asking for Cemetech's experienced opinion on which newer calculator is best to "expand my programming horizons" from my current knowledge of TI-83 Plus BASIC.

Attached is a poll.

I recommend the CE, because it supports C and it is the most actively developed for calculator right now, I believe. The Prime apparently has a very powerful Basic language, as well, if you don't want to learn C.
Just my two cents

I already know C

And doesn't the Prizm support C as well?

The Prizm supports C.

I have a HP Prime, and gets freezed usually. Its basic, HPPPL is very powerfull, but is very tedious to program on calculator. It can't run compiled programs, only interpreted code, so you can't use all if its power.

I recommend you the TI-84 Plus CE or Casio Prizm, if you prefer casio.

The good part of the TI-84+CE is the big community and it has many developers.

PD: With the 30€ of my birthday, I've bought a very used TI-84-SE in Cash Converters. I come from casio, but TI world is amazing

I don't think I really need anything else. With six votes for the 84+ CE and nothing else, I think that's what I'll get unless someone says otherwise.

EDIT: The HP Prime looks awesome as well, although I do laugh at how it calls itself a "smart phone competitor". Maybe I'll get that one instead, depending on the price and availability.

Alright, the 84 Plus CE is coming in the mail. Got it in Bright White

Enjoy the white one; I'm jealous that you get to give it a try! I hope you'll show it off in the Post Your Calculator Collection topic when it arrives. How many calculators does that bring you to now, two?

Couple more, actually. for graphing calculators, that's 4. Including scientific calculators, that's 12. Including cheap four function ones, that's 20.

The TI-Nspire is an awesome calculator, but Since all the recent developments, the CE is looking like a great choice. If not a CE, a TI-Nspire.
