I recently tried a server host called OMGSERV. I conclude that unless you purchase something like a VPS from them (even then, I would recommend OVH) they're services are not worth it. I tried the plan with 'Unlimited RAM'. Not only is this impossible, the algorithm that works out the amount of RAM is very ineffective. I had 24 players running 40 plugins, and the server could barely handle it, peaking at around 2GB of RAM - far from the unlimited amount they promised. A short review, I know, but I don't recommend them at all, and IMO, all server hosts are a rip off, and you are much better getting a VPS - in some cases it is cheaper and you can run multiple servers. Don't buy a server from this company.
