After installing AlYoum on an earlier project, I decided to try Master for a new project.
I was not disappointed. The theme is very flexible and you can be up and running with a great looking site within an hour.
Further customisation is always possible, although a little more fiddly than AlYoum.
If you want a great looking magazine site, or have a lot of content to show off, this is a great theme to go for.
Grab the extra support while you're at it. The guys are very helpful.
