the digital stuff is quite accurate regardless of price, I got a very cheap one from Radio Shack back in 1995 that shows min/max temp and current temp to a tenth of a degree (C) or two tenths of a degree (F) and it matches up well with JFK. Then I got a relatively inexpensive digital weather station in 2005 from LaCrosse and I'm impressed with its accuracy in measuring barometric pressure, temperature, rainfall, humidity, windspeed, etc. I could never get those old aneroid barometers to show me the right air pressure and liquid thermometers never showed the right temperature either. I'm convinced those old instruments from back in the 80s were just gimmicks.
