I just got a Kobo Clara Color over their cheaper models largely for the page turn buttons (and being able to highlight in multiple colors of course). Combined with how shockingly light it is (lighter than my phone), one handed reading is excellent.

Kobo changes their lineup constantly though, the Libra 2 I have (with physical buttons) is no longer available.
My one complaint so far is that the battery seems to need a charge every few days. Definitely less than a week, I think. I can live with that.
I have the Libra 2 and I get about a month from a charge with my normal reading habits.
