Easily calculate cost of an Amazon web service

Today, I was trying to determine how much it would cost to host a virutal server online. While all of the providers had pricing information posted, there are so many choices that it was nearly impossible to get a solid price.

On the Amazon site, I found a cost calculator that was very helpful. From a drop-down list, I just had to select the required services and Amazon presented me with the estimated up-front and monthly cost.
