The June theme from Joomla Bamboo comes packed with classic styling with a retro edge.
They've squeezed a whopping seventeen module positions into this theme, including a mootools based text and width resiser and supplied loads of background images for you so you can tweak this theme to your heart's content.
I particularly like the additional two columns to the right of the main body. I'm not a big fan of columns either side on a website as the user can get lost but I like two columns.
You need space if you're going to sell your space and this theme gives it you you.
You can see the theme live in action over at Joomla Bamboo where they've also just released a FAQ module that you can download. Don't ask if it's GPL or not; I've had enough.
