As Monaghan says - $300 for a fully managed box isnt that bad to be honest, it all depends on the term "managed" - it seems to mean different things to different people.
Our lowest price dedi server is £240 / Month but it's a high spec Pentium 4 machine and it FULLY managed - and by fully I mean EVERYTHING.
Some management plans are only client responsive - i.e. YOU have to tell them there is a problem and you want it fixing... FULLY managed on the other hand should mean that the box is fully monitored and the server management should report and fix things as they happen.
At the end of the day - things do go wrong with servers, it's how quickly you react to fix them that matters
