I just got mine up and running a few weeks ago and this is the route I took.
1. Instead of the Weatherlink module I bought an after market versionn, I went with a BelfryBoy,
http://belfryboyweatherbits.blogspot.com/p/the-belfryboy-clone-usb-logger.html. It is my belief that the BelfryBoy is actually superior than the WeatherLink because it uses a USB 2 interface. The WeatherLink still uses USB 1 so you need to also purchase a USB 1 - USB 2 hub if you went the WeatherLink route. The Belfryboy is ~ $70, so it is a fraction of the price of the OEM.
2. The downside of the Belfrboy is that it does not come with any software, but don't fret. I used Cumulus,
http://sandaysoft.com/products/cumulus to set it up. Cumulus if free, (although they do accept donations).
3. I made my own Meteobridge from a TPlink N150 router,
https://www.amazon.com/gp/product/B00634PLTW/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1. This is identicle to the one that Weatherbridge uses, but it is under $30. You can flash it with the Weatherbridge firmware and you have a 18 day trial of the software. After the trial to buy the software it is $70, (but still far less than the plug and play version.
4. The Weatherbridge connects to my AP so my PC does not have to be turned on to send data to the WWW.
So far I'm happy with the set up. Although it wasn't too terribly difficult to set up, none of this is simple plug and play either, so if you don't like going through set ups and a bit of tinkering then using the OEM hardware/software may be best. The good thing was that there are plenty of sites and message boards that helped me get it all going.
