Alternatives to Swappa. Com? | Android Central

Just wondering if there are any other websites similar to Swappa that you could recommend? I like the fact that they keep a close eye on things and work really hard to keep things on the up and up. I see a lot of good feedback on their sellers which I like. Seems like a safe place to buy and I sold my Rezound there, too. For the past week or so I've been haunting the Swappa site but so far one of the two tablets I want I missed yesterday because I wasn't quick enough so I thought I'd see if I could broaden available site options some. Seems that at least right now there isn't a huge influx of newly available tablets that I want.

Oh, the site needs to accept PayPal for payments.

Thanks,
Deb
