Reasonably priced e-ink tablet

So for my job I take a lot of notes while on the phone (numbers, dates, who I spoke with, etc, etc). I currently use 5x8” mini legal pads to take these notes. I go through a lot of them and want a change. I’ve been looking at some of the smaller eink tabs.

I don’t want anything super fancy or expensive (sub $200) that basically just has the ability to jot things down as I go. I don’t need many bells and whistles (have a Lenovo tablet for watching shows/music/etc and an iPhone.) I just want something dedicated for work.

Any suggestions?
