I was also planning to install the Appareo ESG, because I "live" under the DFW Class Bravo. However, I'm a bit concerned about the inability to enable "anonymous" mode with the 1090-ES solutions, as you can with the 978 UAT solutions. Not sure I will ever "need" to use anonymous mode (legal for VFR only), but it could come in handy in the event the FAA ever goes to a "pay to play" pricing model, as a couple of congressmen keep pushing. Ultimately, price and convenience will probably win out, and I'll wind up with the ESG after all...
