AC Question

Hello!
I want to get a big phone for my mom as a gift. At least in the 5.5 display size. I wanted the Mega 6.3 (she is on Tmobile though) but I have been considering alternatives like the Lenovo phones S939, S930, etc or maybe some other under $200 (new or used).
I just a big display for her for easier typing, reading her Facebook (recent internet and facebook addict lol and to see photos I send her easier).

Any recommendations?
