FYI,
We actually have a Stratus 2 on the way to take a look at. If Walter can get it playing nice, we'll add it to our beta ADSB Weather like the Stratus 1. Obviously, if they go changing things via updates and such, that might break the link. Stay tuned for more, we should have the unit this week and know more by next week.
I've heard good things about the Stratus 2, just have not put our hands on it yet. We've been pushing to integrate the Transciever features for the NavWorx and SkyGuardTWX Vision Pro. Transcievers are gaining popularity as people see how much more traffic you get that with a receiver only.
The ADS-B market is a hot topic and is changing very fast. I think you'll see many more new units in the near future. My advise, Buy what you need and don't worry about the new stuff coming out. Look at the mobile market, it makes ones head spin with how fast they are releasing models.
