I'm with CNS (Commercial Network Services) for almost three years now. If there is only one person using the server (3 - 4 metatrader plaforms at the same time), the value edition will be enough. If you want to have more metatrader platforms working at the same time and don't want your server to lag, you may need to upgrade to a standard edition with 2GB RAM (we share a server between 3 people 15 metatraders platforms working at the same time without any problems).
The support at CNS is great and answer your questions or requests almost immediatly. CNS does all the upgrades between friday at 5 pm (East) and sunday at 5 pm (East) to avoid any service cutoffs during the trading week.
Hope this helps.
