The issue with Hetzner is not the price of the servers. The problem is their connection. The max bandwidth I could get was around 180Mb/s, even though their marketing says 1 Gb/s port. In fact the port is shared.
I have got around 10 servers there and now I am moving away and decided to go with Amazon.
However for a startup with european market it could be a good option.
You can safely move to them, I have several servers, no problems so far, every support request is answered pretty much the same day, and the prices are just ridiculously low. No provider has 100% customer satisfaction rate.
