WeatherLink is required to download the data from a Vantage Vue.  It has a number of options to display weather data both live on a computer screen and to update to a web page.

Virtual Weather Station requires WeatherLink to access data from a Vantage Vue.  It also has a number of options to display weather data on a computer screen.  However, you have to upgrade the version to enable Internet features.

Comparing the two products, there is nothing wrong with Virtual Weather Station except that it is an added cost for the different versions.  I decided not to go with it for this reason.  The Saratoga-Weather.org templates provided much of the same benefits for a donation.  Maybe if weather observations was going to be my main goal, I would have investigated Virtual Weather Station more.  But, my main goal is astronomy so the weather information is a means to an end.
