I recently discovered this site through Mashable.

If you need to re-do your resume, this is the site for you. You put in your information and JobSpice does the work for you. They have several different templates (or you can create your own template if you're a developer).

The site has launched recently, so I'm sure if there are any kinks, they'll be worked out soon! The one complaint I have about this site is that it they don't allow you to very much leeway to format your resume yourself- for example if you want two sets of bullets with different indentation distances, you can't do that.
