Check out GTHost.com dedicated server hosting (https://gthost.com/instant-servers/) - they offer a great list to choose from + multiple locations.
You get what you pay for. It is still very reasonable in my opinion, the stability is excellent, and the support is priceless.

Have a look at servers from decent hosting providers: hostsailor.com (https://hostsailor.com/dedicated-servers/) and coinshosting.com ( https://www.coinshosting.com/index.php?rp=/store/dedicated-servers) (COINSHOSTING-DEDICATED - 10% off).
It's worth paying every penny for hosting services. The bandwidth, is awesome i.e. Speed which I get customizing and lots more.

Can draw your attention to CoinsHosting.com Switzerland dedicated servers (https://www.coinshosting.com/index.php?rp=/store/dedicated-servers-switzerland). The price is really affordable and I am satisfied with it.
As for support, besides speed of responses, I checked to see if they are technically competent and they really do their best to prove it.
