Generally speaking, a Davis with fan aspiration will give you your most accurate readings in the home market, but you’re going to pay for it (to some extent) too. The all-in-1’s are nice, but not all sensors were meant to be placed in the same location…ie wind at 10m, temp at 2m, rain at 1-2m, etc.
I don’t even know what everything is going for right now given the state of the economy.
