I agree with Tom. I have a Davis Vantage Pro2 Plus. I started with a Lacrosse and threw it out after a couple of weeks. I used a Davis Vantage Pro (original) until the VP2 became available. The old system is my backup and still works. The Davis VP is modular and you can purchase the functions you need. Tom gave you a price, note that Ambient doesn't publish their low prices; you have to ask for their unpublished prices.
I also own Rainwise, Acurite, Peet Bros, and others.
