More and more of the Joomla themes providers are offering up free themes but some, like IbolDesign.com only offer free themes from Joomla, and what can be better than that?
I'll tell you what's better, it's when the theme looks like their latest creation; emagazine. It looks lovely and has some very nice features. Seeing as it's free you also have no reason not to go over and support IbolDesign by downloading it.
I actually don't have any issues with it. I've not played with it yet, but I will be very soon, I can promise you that.
