Ubercart

There are other general Drupal tutorials on theming content types, and those will apply to products. We haven't compiled a list of these resources yet but plan to as we flesh out the user's guide. If I were you, I'd just look around the live sites and find something you like for inspiration. We don't have nice templates laying around yet. (Part of the reason is that these will be very specific per Drupal site depending on the theme.)

You certainly don't have to write a template, as there is a default look. And you can do small things to tweak it in your theme's style.css. You can also get the Contemplate module to modify the look from within your site... a great tool for adjusting templates.
