TEXAS INSTRUMENTS TI-83 Premium CE Edition Python – Graphing Calculator – Exam Mode

I bought this as used, like new. Honestly, not a thing wrong with it, packaging a bit torn, that's all. However, this model is in French, but don't let that put you off. Most of the keys are self-explanatory even if you don't speak French. Look up the instructions for the Ti 84 model on the internet which are in English. It will save you quite a bit of money. Also, you can change the language to English on the settings. The calculator itself is very good 😊.

Great, battery lasts me at least a month each time and everything is lightning fast. Screen could be better though, typing with conventional letters is hard, and I found that most of the time I didn’t need the fancy features and ended up using my old Casio.
