In 'north of 60's' little tirade, I think he lost track of the overall subject. I think the consensus of Davis owners is that their quality is actually quite fine and their service excellent. What should be understood is that for extreme climate conditions (like north of 60 degrees), no hobbyist weather station is likely to work correctly below -25C, so where you need a snow tractor for months out of the year, only a industrial station (at $3K to $10K) may be needed to survive the harsh conditions and report reliably .. but not everyone can afford a RAWS-class home weather station (wish I could).
For more temperate climates (where most of us live), the Davis Vantage Pro line is arguably the most accurate for the money (<$1k).
Ta Ta, 'north of 60' .. it's been real, just sorry it wasn't more illuminating (except for the demo of bad behavior).
