I guess, if started with 3D printing, the user will find out that 350EUR are wasted, since for 100EUR more, you get some Prusa Clones with heat bed, normal print bed size etc.
With my K8400, I have the space I need for printing, that is enough at the moment.
But having E3D stuff added to the K8400 makes it a real good 3D printer.
I thing, for people who do not like to change and improve a little printer, i will probably work.
Have the little printer on the desk is even more an eye catcher, despite the smell and noise while printing.
But as a gimmick really nice.
But if one is more interested in improvements, and experimental stuff, the Nano is not made for that (which is was not designed for).
I guess, a larger K8400 would be good idea.
