I don't know if this addresses your question or not, but I believe that when there was a problem with the Davis equipment, they jumped on it and corrected it. The other competitors for this price range are, in my mind, not as well engineered. Nor do they perform as well. I have even built my own instruments, dating back to the Heathkit line, and can tell you that the need for constant recalibration, dead sensors, etc... is rare for Davis. There are inherent strengths and weaknesses in ANY price range. You need to really compare and do your research before you buy. For instance, what is your prominent weather condition? Which station is best designed to monitor that condition? What I am suggesting is that a problem with a station is no more irritating than the WRONG station for your needs. As I have stated in this forum before, I have a VUE and living in NW Louisiana, wind is not a major player-- temperature, rainfall and such is. If I lived in a windy location, I would opt for the Pro2 for the ability to isolate the wind sensors. Back to your original question, I have heard of issues with both Davis and Rainwise, two very fine manufacturers. Likewise, I have heard that they take that seriously.
