Any Chance of Remake / Upgrade?

[rprosperi]

One reason the 35S pricing has skyrocketed is this calculator is one of the few RPN machines still approved for Professional Engineering exams (I think the only other one is the 33S, which no one likes for multiple good reasons) and there are books and preparatory courses one can take to study/prepare for the exam built using the HP-35S.

The other is that too many well-heeled but stupid HP collectors have far more money than brains. A perfect storm for greedy eBay sellers.

Both factors lead to incredulous listings like this. It's sad....
