I'll let Paul (Hi Paul!) continue guiding you with the loggers, etc.,. I do want to interject this though...now will undoubtedly, without a question, be the least expensive time to get all the sensors and setup that you want. The Vantage Vue is an all-in-one unit where you have the wind and all the other sensors combined into one unit...recommendations are for getting the anemometer up as high as possible but the rain gauge and temperature sensors down around four feet or so. This isn't possible with the Vue. The VP2 that Paul mentioned does have a wired but remote anemometer so that it can be installed high in the air while the rest of the station is down in the 4-5' zone. The VP2+ comes with solar and uv sensors. If you want the whole enchilada then now is the cheapest time to buy it...buying the uv sensor later is expensive, though the solar is a good bit less expensive to add later (the solar, in my view, is more functional/useful, too).
So, think about what you really want before plopping your money down for something...if you have to way a while and save up more money, then so be it. And, as for getting the anemometer up at the "recommended" height (31'?) few of us attain that height...there is always a comprise in things...and that is ok, too. The Vue is by and far a very good system...better than most. The VP2 and VP2+ are modular and modifiable.
Anyhow, just wanted to throw my 2-cents worth in.
Have fun and enjoy whichever station you decide on....for the price point you can't go wrong with a Davis.
Best wishes,
Ed
