Hi Jim,
Can you tell me how long your Costco has had these WS and what they are charging for it? I visit the big "C" about every two weeks (including last night) and haven't seen them. It's just as well, the Rainwise Mk III is still in the mail and the CFO has reached her limit. If I bring home the Acurite and it does more than the Rainwise, even superficially, well, let's just say that there would be some splainin' to do!
I'll probably get one for my son-in-law for Christmas though. He's developing an interest in weather from hanging around me too much.
