6 minutes from the time I downloaded it till it was running live on the site. Simple as 1-2-3 installation, create MySQL db, upload script files, run admin and you're up and running. Very flexible site with a lot of options and author has left the header and footer clean of junk so you can put your own touches on the site. Typical of MySQL driven sites, this one has quick response time. A real bargain at this price.
