I still have a Pocketbook Lux 3 in use. It must be about 10 years old now and still works beautifully (even the backlight). One battery charge usually lasts me weeks, even with heavy backlight use. They are made in Europe (Switzerland) and run some flavour of Linux. They‘re not rock-bottom bargains, but the cost of the entry-level model seems quite fair in my opinion (€107). pocketbook.de
