Which Railshoster for a productive application in US?

Dear Receiver and Forummembers ;),
I’m looking for a hoster in the US which provides the best enviroment
for a Ruby on Rails application. This should include Managed Server
Support by the Linux Administration (I have no experiences with Linux so
far), Backup and monitoring.
The load on the server will be around 200 active customers per day (so
really less, but the need to be served quick)

Which hoster can you recommend? Which hoster do you use? Which hoster
should not be used for such a project?

EngineYard. However if you can’t afford that, RailsMachine is going
to be the next best but the support is nowhere near the same level.
