The 19 is extremely simple to learn and use in comparison to the 10B. It is far more powerful and has many more functions. It’s not worth saving a few bucks to put up with the 10B. Not that it doesn’t work well. I would rate it third behind the 19 and 17. Possibly fourth, because I still love the 12C, which still holds as the standard of the industry. The 19 is the easiest to use, but in some ways the 12C may be easier to learn with all the courses and classes available for it.
I haven’t seen any courses written around the 19 or 17, though the CCIM courses use the 10B. I teach a generic three step process that is quite simple to use on any calculator. You can then discount a note on any calculator - even the nerdy - but functional Casio watch calculator. I used to have one, but I do way to many un-even cash flows to use a simple calculator.
