I bought & installed the WS-1400-IP back in February & have been pretty pleased with the purchase & operation.
I had been putting off getting a weather station for years as I wanted a Davis VP2 but the price was right for the Ambient & what it offered.
The station was online within a couple of hours of receiving it, WU records all my data & I can view my conditions from anywhere. I don't find not having a console a real problem & I don't have to have a dedicated computer running for data storage. As Arktikos, mentioned it is supposedly compatible with Meteobridge if/when the time comes.
While I would still like to have the Davis, the extras needed to go online seem pretty clunky/$$, where as the Ambient is turn-key.
Can't comment on the Acurite, though I have noticed that in my area, many of the outlier high temps on WU are from Acurite stations, though it could be caused by how/where they are mounted.
Also, meant to mention that my rain totals are pretty consistent with my CoCorahs data, usually .01 higher.
