Are you willing to use Linux?
I use this service for my blockland server as well and i'm able to host one server without any lag, haven't tried anymore. I'm using the lowest package at the moment running linux.
Do you find it difficult at all on linux?
yours is really unstable though and crashes often
That was the CityRPG mod and a bug when buying lots, my server has been up for days without a crash. Personally i'd just go with the second package so you don't have any issues.
this -> https://vpsdime.com/Very great. And cheap also :VBut I think 2gigs of ram would do it.
I am currently using DigitalOcean, so far I like them.
