New ereader

Hey guys, I have a 2022 kindle basic but I really miss having warm light so I am looking to buy a new e reader, I have been looking at PW11 or 12, Pocket Verse Pro, Bigme B6, and kobo clara bw. What are your recommendations? I'm a bit on a budget so I either buy used or new if I find cheap ones

Edit: I want to use Koreader
