Thanks for the welcome and the info, garthbock! I didn't put it in my profile, but nice to see a 'neighbor' here. I live just a bit southwest from you, in Jacksonville, IL.
I definitely want the ability to push data online. I've already got my 2310 hooked up to an old laptop that's pushing data to WeatherUnderground (KILJACKS2) with WUHU, and that's all working well. I'm just irritated by the frequent bad wind data that I'm getting from the 2310 and think that a higher quality station would solve the problem. I've wasted hours of my life on the 2310 in running/replacing/re-running cables (telco vs Cat5), mounting & remounting the sensors, tinkering with ferrite clamps, etc. I'm feeling like it's time to cut my losses and just go with a better system.
Like you, I have thought about going the route with the Envoy as well, because I almost don't need a display unit as I'm more concerned about having the data online than from the display unit only. I am happy to flip open a notebook or fire up the iPhone to check on the weather at home, whether I'm sitting in my living room or from across the country.
I've looked at the 968 online (reviews & looked at the manual), and that does seem to be a much better unit than what I have. At $200-$250, it's certainly more in the price range of what I'd like to spend, and it has a serial port built in. The sensor mounting options are a bit more flexible than the VP2 as well, since they're all independent. Though I want something that will last and be accurate, and that's where the VP2 seems to trump all of them.
And yes, I'm ready for the opinions. Bring 'em on!
