Which VPS is better to sign up with - rockhoster.com or hostsailor.com?
Any ideas?

Please, be more specific... I mean requirements: disk space, bandwidth, server location, budget?
Happy with Allwebhost.com hosting. High-speed server performance. Dedicated and passionate customer support + useful tools for the website!

Look to do business with a web host that offers support in various means. Whether it's a combination of phone and email or phone and live chat.

Recently moved to NetShop-isp.com.cy after a nightmarish debacle with another hoster. Support has always been good (ie they actually read and answer the questions you ask), and they understand the technology. Recommend their Netherlands VPS solutions.

Why not give Profvds.com vps in Slovakia a try?
The system works great, and their MySQL servers work better than any we have tried to date.

Give Rockhoster.com a try. The OpenVZ VPS comes with complete root control and SSH access. Starting at €4.59/mo.
All the services comes with high speed network to offer best latency and ping worldwide.

Great service, support is ALWAYS prompt and helpful. They even reply on weekends.
Fantastic host. I have used a couple of others and finally switched to Rockhoster.com solutions.
