I suggest you to focus on a German, France or english data center. There are not so big and organized like the U.S.A.'s ones but there are cheaper and closer to you (smaller latency, faster pages loads).Ping tests from Greece:Ping time response to my previous server at U.S.A: around 180 msecPing time response to a German one: 6-7 msec
I personally use Hetzner (hetzner.de) but you will have to setup many things on the server by your self. http://www.hetzner.de/rootserver_en.html
