sitekreator is a little bit more expensive than that (http://sitekreator.com/sitekreator/pricing.html) but it does offer a lot that most of the alternatives mentioned here do not - how about a CDN, full Google Apps integration and some of the most advanced Photo Gallery Visualizations in the industry, just to start? ;)
