Dilly, I have the vantage vue, and despite the fact it is an all in one unit, it really is a very very good bit of kit. In your location it will always be a compromise, same as mine, but I found a removable scaffold pole about 15ft high, upsets no-one and gives a good balance between rain and wind.
The others are correct in that you really need the data logger to go with it, BUT there are a couple of people on other forums who have built a superb alternative to the davis one, and I can speak personallywhen I say it works really well.
Have a look on www.wxforum.net and look for Belfryboy. His works as a logger and interface and is a fraction of the cost.
regards
Woody
