I have the OS-WMR-968 station and it has served me well. The only problem I have had it water got into the anemometer transmitter and shorted it out. Other than that it's been a great station. The only two draw backs are:
1. it measures rain in 0.04" incraments and not 0.01" However the guage can me modified easily.
2. the frequency at which wind speed and wind gusts are updated.
You can find these stations for under $200. If you want a recommendation on where I would by it, send me a PM.
The biggest draw back to OS is. I've heard there customer support has a lot to be desired. Remember this is hear say. Not personal experience.
As for the LaCross stations. I know nothing about them.
