recommendation needed for dedicated server hosting

Hi, I recently went through a horrendous experience with two different hosting providers. I'd like some recommendations on excellent hosting providers if anybody has some. My key priorities in order are: 1) around-the-clock, technically competent TELEPHONE support (webchat support, message boards, email based support etc. will not do!) 2) reasonable hosting fees (no more than 300/month) for a dedicated server 3) services for the following - backup, OS upgrades/patching, security If anybody has been with a company that they're happy with for at least a year please leave some feedback. Thanks!
