My wife broke the screen of her iphone 5c again (I swear they make those things so they break on purpose). She's been using my S5 for the last week to take pictures and stuff and I think I've finally convinced her to go android. However we are 6 months from upgrade so I started looking around about picking up a used Sprint S5 online. Anyone have any experience with sites like Gazelle or Swappa? Amazon also seemingly has a limited selection of used ones. She'll probably end up upgrading to the S6 in 6 months anyway so I'm basically looking for a cheap hold over. Only catch is it needs to be good enough to not put her off Android and drive back in Apples awful clutches.
