DM42 vs DM41x vs DM43

[Marco Polo]

Even being a long-term RPL models user, i like also using RPN with my 35s for daily simple calculations.
I think the 35s has some nice features (solver, a few built-in uom conversions, plenty of memory, decent keyboard and good overall construcion)
Anyway, I miss some 48/50 features that i would like to have in any calculator: named variables, capability to save/load programs to pc, good display, customizable keyboard.

I am looking into Swissmicros product and find the DM42 a good compromise which could fit well as a 35s substitute, but the raise of DM43 and DM41x added more choice.

The DM42 firmware is continuosly improved by mr.Okken effort and in perspective more features might (i hope so) be added to Free42/DM42,like for example the embedding of the UOM conversion program made available by a forum member, a more friendly way to use the solver, etc.
The DM41x, correct me if i am wrong, is more or less a 41cx in a nice dress and with some additional features, but no significative improvement respect to 41cx functionality should be expected in future.
The DM43 seems to me a calculator for real hardcore RPN users: quite amazing, but too complex and too math people oriented for a chemical engineer and still in progress.

As all three calculators share more or less the same hardware, should i wait for the release of the DM41x or get now a DM42 and in case flash the definitive DM43 firmware?

Thank you
