Stable hosting for MyBB Community?

[Herstin]

Hi all, I'm hosting a MyBB forum and need a stable hosting with guaranteed resources.
Looking for 2 vCPU, 4GB RAM, SSD storage, and decent uptime. Budget is about $20/month.
Eastern Europe or Germany location would be ideal. Reliability is more important than raw performance.
Any comments on HostPresto.com and Regvps.com hosting services? Are they reliable? Other hosts?
