I rent a "root server" from hetzner.de. It has been working amazingly well for about five years now, even pre-dedicated DCS server and even before I started playing DCS and found an amazing group of ppl to play with.
If it's worth the price? Nah, you'd be better off buying a server of your own (if you got internet that's good/stable enough for your needs that is), it'll be cheaper in the end.
If you're looking for a more SaaS-oriented hosting platform I have zero input, not my thing :)
