Well i was stalking this deal for a long time and had cold feet, now had to upgrade to briefcase to get it, but its well worth the purchase and the effort, what made me take a leap was checking out the speed of the sites built using it, the cdn itself it so optimized that its blazing fast, so just stacked 2 codes and i am now set for all of my personal sites and i can now also help my friends set theirs up.
so far have been amazed by the experience, hoping they add a few new themes occassionally, i just found that the stock photos that the ai uses to create the websites seemed grainy, never created the site, so might have been decent in the final version. This i believe is an investment that would provide a ROI pretty quick.
I would definitely recommend the product, glad that i took a leap of faith.
