I do not like RPN I prefer arithmic input

I had in the 27s a lof of solver equations with one drawback. There was no naming of equations and you could not reorder equations.
For a new calculator i would like an option to group calculations, if a caculator with such options exist.

passive component caculations
Filter calculations
Stepup converter calculations
Thermal calculations
etc.

it this is possible, that would be extremely helpfull

I want longer variable names so I do not want to be limitted to one char names

I hope to find some advise or more info here before I decide.

The 35s might be a good option at a decent price. Though purist won't consider it as a true HP. But it offers a lot and certainly matches your demands.
