Offer me a right server provider ...

Servers from planethoster.com and legionbox.com are well-balanced and low cost and I hesitate which way is better for me to go and why?

Does the provider offer staging environments for testing changes? It will useful for my websites that require regular updates.

As for professional web hosts, I know GTHost.com and Neironvps.com are good places for getting dedicated servers at reasonable rates.
Their servers are excellent too, very fast and I've never experienced any downtime.

Choose a host who understands your specific needs, and who can sit down with you and talk about what your needs are, and how that host can accommodate for those needs.
If you ask me, I am happy running my sites at Hostnamaste.com budget dedicated server - Carrier Neutral Facility - Redundant & Reliable. ISO and Security Compliances - Cisco Network across all layers.
They are reliable and trustworthy, so I suppose this might be suitable for your request.
