If you are serious about building an E-Commerce business then you may well incorporate some of Fantasticos features into your site, but as with most free things, the site scripts will not have the features you require as you develop your Main Web Site.
If you are looking for Easy to use Web Site Building Software that you will grow into, not out of, then you will want to review my following recommendations.
Xsitepro is the website builder of choice for many Internet Marketers. This versatile software comes pre installed with numerous templates to create multiple styles of website. No Html Required!
Content Management Systems - CMS
Interspire Website Publisher is a content management system which makes it easy for non-technical users to create and maintain fully functional websites.
As with Xsite Pro, Interspire has far too many features to outline here, before you buy any Web Site Building Software i strongly recommend you investigate the best solution for you Static Web Site or Content Management Site.
