Looking for good offers on an unlocked GSM smartphone that you might wanna pass on. Battery life should still hold at least. Don't care for good physical condition -- it just needs to be 100% stable and works.
Around $100, give or take, if I can be persuaded to take the latest feature. Not too sure about WMP -- do you feel like the apps are plentiful on WMP? That's really my only concern.
Edit: No real budget set in mind, if a damn good phone can be had for $200, sure.
Otherwise you can just purchase a brand new Moto E for $120 or Moto G for $160. Unlike the Nexus phones both have microSD expansion slots up to 128GB if that matters to you.
