DM,
Take a look at the iLevil and the Clarity. They will offer ADSB WX and Traffic. Just keep in mind that unless you get an ADSB in/out or Transceiver, your traffic will be very limited. NavWorx makes a nice transceiver, the ADS-600B. I'd consider it more semi-portable. We are also working with FreeFlight as they have the Ranger and Xplorer. Stay tuned to this market, it's moving.
