I know a bit late posting on this but I have been very happy with GreekGeeks.
With my one account I am actually supporting two separate WeatherCat webpages each with frequent realtime updates. Additionally GreenGeeks support is always there with most issues being able to be resolved with a chat session. I know they are not the cheapest but still priced reasonably well and I will certainly be staying with this based on the great service I have received.
