PULLED THE TRIGGER...
OK, I signed up to be part of the "Group Buy" going on through the Ercoupe Owners Group -- they opened it to like-planes, so the 150 was OK with them.
I really do not expect much of a discount and I really do not beleive it will arrive in time to get the $500 faa taxpayer give-back, so that aspect does not concern me.
I do want a high-quality ADSB out sytem that is easy to install and will work for at least 5-7 years without issues.
Folks on the Cessna 150 Club are saying great things about the SkyBeacon (wing version) so I am going to give this a try.
Thanks to IFly and everyone here for helping to sponsor this product - it is the only way I can really afford it.
