Does anyone here keep or know about weather stations? Last time I seriously monitored the weather we dripped out to empty a calibrated glass beaker and drove 5 miles down a flooded road to read off the river height from a post. Things have changed a bit since then

As you can see if you follow the link, there's quite a range of prices for what look like very similar services. Aldi had an automated weather station a week or so ago for about $50 which seemed pretty slick from the catologue, though I didn't look at the specs. Does anyone know if value goes with price for these things?
