I am so pleased with ElegantThemes. Their theme, Divi, is one of the most powerful and simple to use page builders on the market. Hands down. I've worked with them all. Been doing WordPress sites for about 10 years now and I've never been this impressed with support of a theme or plugin. Sure, you have to pay for the theme, but the support alone is worth it. I had an issue with some WordPress core files and they even helped me there. Bottom line, do business with these guys. They won't do you wrong!
