I choose a 500€ phone with the stats of a 100€ china phone for repairability and longlivety, also put a lineage based android on it.
Still have it after 5 years and getting security updates for a long enough time that it could hold out longer than 500€ in china phones.
Still havent had a reason to fix it, maybe open to let the water out but nothing else.
(Its fairphone but i consider a shiftphone as my next some time in the future)
