Take a look at the successor to the fx-85GT PLUS
Unboxing the new addition to the Classwiz range, the fx-85GT X. A stripped-down version of the Classwiz. Same display, same technology, but less features than the fx-991EX, this calculator will take the place of the current fx-85GT Plus, which I imagine will be discontinued going forward. Available from January 2019.
