Which kindle(?) to buy for downloaded books

Hi!

I want to get more into reading but books can be expensive and bulky.

I thought I'd buy a Kindle (or similar) since those screens are pleasant to read on, but I don't know if there's anything specific I should be looking for piracy wise.

Apparently amazon has added support for epubs so I'm hoping it'll make it easier to load with my own downloaded books?

Also, the version names/models of kindles are crap.

Edit2: I've decided I'll buy a paperwhite kindle (2020 version). I found a 2nd hand one, like new, for 80€ with a screen protector + magnetic cover. This way I'm still not supporting amazon :)

Edit: I seem to have posted this same/similar question yesterday but I have no recollection of doing so. If this is something you're interested have a look at that post.
