Information Zone on HP 48 series

[Carsen]

Greetings to all! I hope you are all fairing well!

Today, I come to all of you in the HP Museum for your wealth of knowledge. I need to know all the differences between every calculator in the HP 48 series. Which is the best one in your opinion? Memory, RAM, features between every make and model? Anything else to add? Where to find such a prized gem?

My main goal is to try do decide which calculator in the HP 48 series to add to my collection.

I am only 20 years old and that is the main reason why I know so little about HP Calculators. Plus, it's hard to collect them too because most of the "cool" models were produced before I even existed! But despite my age, I am very passionate about HP Calculators!

My apologies if a thread similar to this exists. I tried to find info in the HP Museum but alas, no results. Thank you all for your knowledge, help, and time!
