Where to buy an affordable used phone?

I know new phones are expensive but you don't want a used phone. I tried that from newegg.com. A very good site and the phone was beat up and the battery was already shot. It wasn't much cheaper than buying that model of phone new would have been. Check out this site. www.gearbest.com. the phones there are all unlocked for global use and the are all very good phones for what they cost. But if you buy a phone there pay for DHL super expedited shipping. Otherwise it will take months for the phone to get to you.
