European Second Hand Online Markets Italy, Germany, Austria - Suggestions?

Hey Europeans,

So I have looked around a bit, but I'm haven't really found many European websites which people sell phones on, in Europe. Of course there is swappa, but it seems pretty barren at the moment for phones in the EU. Failing this, any reputable websites to buy devices new based in Europe. If you know any good sites that you could reccomend I would appreciate the help.
