I was out running errands today, and thought I'd try to locate one of these color-screen weather stations that I saw on Brickseek/Walmart.
There were a few in the Dallas area, at varying prices. I went into the Carrollton, TX, store to find that they had the one I wanted, marked down to $25, but rant up at $10. MSRP is $49.
In addition, they had at least 30 mixed models, but all the rest were B&W LCD displays, so it looks like they clearing out old stock.
They also had some of the higher-end weather stations that do wind, pressure, etc, for a little as $25.
Here are the links for the models that I saw in store. YMMV. Good luck!
