Stable server provider ...
 

Comparing servers from black.host and hostsailor.com, what should I do?
I mean which way is better to go?

It has been more than a year since I have been with Hostnamaste.com budget dedicated server and I can most definitely say that they are the most professional, understanding and hard-working host I've ever come across. The customer service has been extremely quick, efficient and friendly. Support it is the best.

Check out servers from decent hosting providers: coinshosting.com (COINSHOSTING-DEDICATED - 10% off) and allwebhost.com (50% first month discount).
They truly have the best services. Not to mention, great speed and amazing support.
