A dude I work with has nothing but praise for GoGrid - he told me setting up a machine behind the balancer is super simple... I'll see if I can convince him to share his experience.
Setting up a server behind a load balancer is super simple. The only issue I have with GoGrid is when you have to setup a few machines with complex configurations or change the setup behind a load balancer. GoGrid has followed up with me though as you can see in the comments and advised that most all of my concerns will be dealt with in the next update. So I'll probably after update my opinion significantly after that.
Why do you need servers on the West Coast?

Hey, I'm Shawn. It was to keep latency low for clients of ours on the west coast. We have to complete every request within 350ms including network time and when we were serving west coast clients from the east coast we were unable to do this due to network latency.
