I feel you with the low funds man. I can't check right now cuz I'm on the way to work but I read recently that the Rezound was $80 on Amazon with an upgrade. Maybe check there? As far as older phones, something like the Inc 2, Samsung Charge, and Bionic should all be relatively low priced and allow you to keep your upgrade until you feel ready financially. People buy phones from Swappa, I haven't before, so that's another avenue as well.
What is your price range?
