Instrument to measure wind speed!!

I really love windy weather and rain and snow as well. These three different weather has different temperature and are of different  types.So I like analyzing these and read each with specifications. But I always make sure one thing that the instruments I'm using are of good features and quality otherwise it won't give me appropriate or correct results to analyse. I buy branded Instrument to measure wind speed,rain gauges,data loggers and other from weatherstationary.
