I went the Davis route, and was very happy with them! I found a device on Davis website that allows you to connect their sensors and any other weather sensors to this unit: http://www.controlbyweb.com/x320m/. It uploads the weather data straight to the web without a computer or usb, etc! ... I graph and log weather information over time and can monitor my station from anywhere I want because it's all accessible over the internet! Like I said, you can use it with Davis or any other weather sensors... Hope this helps if you haven't already decided.
