Any low-cost Virtual Private Servers able to run GeoServer?

I just deleted one of my Amazon EC2 instances where I had GeoServer running on it. You can spin up a micro instance for 2 or 3 cents / hour depending on linux/windows. But I only use them to play, I couldn't comment on using them in a production environment (you would probably have to use a larger instance which costs more per hour). If you are just developing on them, you can just start them when you need them and stop them when your done and that will save you some cash (you can do this easily in a batch file).

Also, don't terminate the instances--that removes them permanently!

Update: There are some opengeo amazon machine instances already present...you might be able to launch an existing AMI (although it didn't have a micro-instance option for me).

Another Update I found this while trying to find out information on the existing AMIs:

I really like http://linode.com
I run http://postgisonline.org on their smallest VPS which costs 19.95$. It is a Xen virtualized server. You can choose from a lot of different Linux distros, and there is plenty of great guides how to install and manage the server.

I have not tried to run GeoServer on it, my application uses MapServer to produce the maps.

In addition to Linode mentioned above, Slicehost is another popular low-cost VPS service. You should be able to run GeoServer on any VPS as you should have control over what software is installed.
