here's another...
search circuit cellars website you'll come up with a ton of designs.
If you want something reliable and accurate you will have to spend some money.
Check out Maximum for wind gauges. Do a google or click here:

"reliable" and "inexpensive" are at best orthogonal, if not downright contradictory...
I just want the stuff to work. Had a heathkit weather station for a number of years, but when I worked 2m packet, it thought I was on jupiter -- temperatures zoomed down and barometric pressure went really, really high (and that was *after* I put RF bypassing on a lot of high Z nodes, and shielded the thing).
I've had no trouble with the Davis Instruments stuff. Currently run Vantage Pro2 stations at a number of locations, using the Weather Display software.
It's not cheap, but it works.

The Dallas 1-wire system has been popular. North American mfg is in Mexico and I saw that a European mfg started to build the same design.

You might like to have a look at the Silicaon Chip website - they published a weather station not so long ago - I read the articale at the library so don't have a copy, but a search of their site should find it - the windspeed/direction part looks very neat and should be reliable and cheap

Texas Weather Instruments developed the 1-WireT Weather Station, using technology licensed from Dallas Semiconductor (see Sensors magazine June
1998), to solve the problems of attaching multiple cables, power supplies and consoles associated with weather instruments to a Windows PC.AAG Electronica (Mexico) makes the kit of parts ($75), the TWI is only an assembled unit.
