Just re-launched a site moving from Joomla to Drupal + Ubercart.
http://www.thunderdogstudios.com/
You can check the store out at:

The products page is pretty customized, but works pretty well in modern browsers. The store has been working great and TD has been selling out on their different products pretty quickly.
Individual products page

They are selling vinyl toys, posters, and maybe clothing in the future. The page automatically pulls in user details, which has been quite handy. I utilized jScrollPane for the scroll effect and a whole lot more jQuery plugins.
