Too many calculators?

Although the original 32Sii indeed had very little memory, the DM32 has >50 more memory and can use it much more effectively. Also, you can upload/download programs between PC and DM32, similar to how this is done with a Dm42, but they are not directly compatible with Free42.

The DM42 does include an Equation Solver, styled after the one found in the 17BII/19BII/27S, even though the original 42S did not have this. And of course the DM32 has one just the same as the 32Sii.

I'd say if you are more comfortable with, and need the extra power of Free42, then a DM42 is the way to go, but OTOH if you are more comfortable with the far easier to use, albeit less powerful 32Sii, the a DM32 is a better choice.

It's easy to recommend, but what is best can only be determined by you.
