Looking for e-Ink Device 9"+ compatible with PDF & Safari Queue

Hi,

I'm considering upgrading from my Kobo Aura ONE. I need a device with decent DPI, recent android version (for Safari Queue) and that's available in Europe.

So far I've looked at the Onyx Note S but the resolution is way too low. The Boox Note 10.3" looks okay and the Max 2 would be great (albeit very expensive).

Are there other devices out there that might fit this criteria that are available in Europe? And if not, are there any sub $300 devices that might fulfill these needs? (less than $300 because imports are always a gamble without warranty)
