Another user of Davis VantagePro2. Wireless version been up on a 14,000 foot mountain for 15 years. Had 2 destroyed totally by lightning. High winds (100+ mph) also frequently wreak havoc so have replaced anemometer and cups (keep a set on hand) every so often. Biggest problem is ice and snow buildup on cups (only solution is to clear by hand or wait for sun to melt off). Tried a Vaisala with ultrasonic anemometer and heated tines to no avail (12V heating don't work very well); also issues with data transmission that I never could resolve.
VP2 is expensive (wireless is what I use and wired is cheaper) but Davis will rebuild the station for a fee (never tried but got close) if it starts to fail. AS I said, rock solid in extreme weather.
As far as software, been a long time user of Weather Display. Really a great program and kinda reminds me of
Blue Iris in that it's a single developer who keeps cranking out updates. One price is good forever though. Never tried integrating it with BI but I'm sure it's possible...
