Blu Life One X2 (their newest, 64gb, 3gb, Marshmallow) was a phone I was seriously considering before I caved and got the Axon 7. The only downside I saw was Blu usually doesn't update their phones. Currently $250 on Amazon. Great phone for the price!

ETA I also still have my old Amaze in a drawer. Great phone, but it was dying a slow death...
