I own a wireless, Davis Vantage Pro. Now Davis has updated this system to the Vantage Pro 2. The vantage pro 2 most likely has some updated "weather junk", and componets. I believe the wireless range is advertised at 1000 feet (perfect conditions, and terrain). The one I have is rated at 300 feet. Which operates very well for me. My station is probably located 80 feet from my house plus a little more distance inside to my console. I personally would not buy a weather station that isnt wireless. Wireless are a bit more $, but well worth it. The only wired part of the station is the anemometer, (wind speed thing). That has a telephone-like, cable which allows the anemometer to be positioned higher than the weather station unit itself, where the cable is plugged into, than wirelessly transmitted to your console. I also have a the solar panel on the outside station, along with a battery backup. The small 6-volt, camera battery is used to transmit the weather packets from the outside station to the console inside your home. I have only changed the battery twice in 5 years. So I'd think without the solar unit the battery life would still be almost 2 years.
As far as the software goes, Davis provides software, which is recognized by the, Weatherunderground, website. Which I assume is the site you are referring to. Therefore, Ambient weather is not really needed to upload your data to their site. Regardless of what you have heard. Actually the software I'am using is provided by the, Wunderground. I have a older version of Ambient (bought with the station), which I dont use. Its a computer "hog". Unless you have a old computer to run only the weather station, you will find that Ambient, will boooog down your system. Right now I am running my station off my old computer. I wouldn't need to, but it was easier to do that than transferring it all to another system.
I'm sure there are many stations to choose from, I know that Davis are suppose to be the "Cadillac" of personal weather stations. There price tag isn't cheap, but I do like the unit I have.
