I think it depend on how much you want to tweak the server and which framework you use.

For me, I use Zend Framework and AWS. So far so good and AWS release my loading effort in maintaining the whole system.

In my monthly bill, the most expensive AWS service was EC2 and RDS.

FYI: AWS Free Usage Tier charge me less then $1 every month during my development phase.
