Dumb question, but what kind of calculator should I buy as a student?

I am on the 3rd semester of my degree, and my ti-84 is dead. I know only certain ones are allowed on the FE exam, are ones allowed on the FE adequate for classes? I am not really sure what functions I actually need. I’m not poor but $100 is not a small amount to me, would like to avoid needing to buy another one
