One thing to note about Hetzner, in addition to high US latency times, is the initial setup cost. For the EX4 (core i7-2700, 16 GB ram, 6 TB HD, 49 euros/month), the one time setup was 149 euros. However, I just checked and the setup cost for this server has dropped to 49 euros. I'm not sure if this is promotional or permanent.
