Anyway to preview themes?

Before buying and wasting money on a crap half assed theme, i would love to find a site that shows images and previews.

There was a site called dashboardthemes but no longer exsists.

You can on xbox.com, give me a second I'll find the link for you. Also, they don't have all on there but they have majority

**UPDATE**OK I guess nevermind because now I can't figure out a way to on there. It used to be really handy
