Title. It's dirt cheap right now, and i'm tempted. But i kinda want an automatic or at least mechanical one...does such model exists?

Title. My 50G discharges in a day, and i can't find anyone to fix it, My 35s is having some issues on the lcd. The swissmicros option are 2-3x the price of an HP prime where i live so...I just want a calculator to do "basic" engineering stuff on RPN.

Will this do? Is it as easy to use the RPN mode as my 35s? As in i just power it on and everything is good to go? Or ill have to go through a plethora of menus every time?
