If I werent with SuccessfulHosting.com, I would definately try Site5. Don't worry this is related..

The reason I would try Site5 is their progression meaning they are always thinking up new ways to offer more and better their service. That kind of dedication is something I like to see. Of course recently they havent been getting the best of reviews but thats one factor I would look for that hasnt been mentioned already.

Plus the common ones, excellent support and excellent uptime.
