Elegant Themes must be the best value for money among the WordPress commercial themes. Not only their themes are really elegant (how refreshing to see an adjective used appropriately for once) but what they charge for such a vast range of themes is bordering a steal
I wish I found them earlier. My previous purchases from ThemeForest would have paid for many years' subscription fees.
Especially important is you average about 49 cent a theme and if you plan on using for many years and need developer member ship, the $249 is an outstanding way to go. Developer is $99 a year and is needed for the plugins and being able to use ET themes for developing clients website.
