I've been talking to Amazon Customer support, and while I won't get a new kindle (Obviously, my own fault, and it's more than a year old too), they're offering me a refurbished Kindle PW with the standard 1-year guarantee, for 91€ (as opposed to 114€ for a refurbished PW without the discount or 129€ completely new) so I'll go with that
I can still buy in other shops via Calibre, and while I may not be able to use a library, the ones near me don't support that option anyway, and I can live without it.
Thanks for all the tips guys
