I have found what appears to be a reasonable deal on an un-used uavionix SkyBeacon. The story supposedly goes like this...

Some Guy #1 bought it and didn't use it, because they upgraded their panel.

Some Guy #1 then sold it for $1800+ to Some Other Guy #2, who bolted it into his newly purchased (used 1968) Mooney, then started the Mooney to power up the unit and test it, only to find that the Mooney's old transponder didn't work. So he removed the ADS-B unit, never having flown it, put it back in the box, and upgraded his Mooney to a new Garmin Whiz-Bang 5000 transponder that had ADS-B built in. The never-used uavionix wingtrip ADS-B unit is now for sale, at a good (but not too good to be true) price of$1600.

I don't know Jack **** about avionics, have no test equipment, etc. I can solder red and black wires together, but that's about it.

So my question for this groups is: other than obvious physical damage,. can anyone tell me what I can look for to see if this is indeed an un-used, not stolen, legitimate, and register-able ADS-B unit? Is there a website that I can look up and find out if this has been registered, or listed as stolen, or a recalled/defective item? Is there some paper form that needs to be un-marked and bar-coded etc. with the unit, and if this form is not present it means that someone has already registered it or it cannot be registered?

Unfortunately, this is for a Cessna 172, and I'm feeling a little less scofflaw-ish today than I was previously. The unit I am (hopefully) buying tomorrow is a TSO unit.

The Echo + Skyfx GPS bundle gets you the same "out" capability for \$400 less money. And if this particular unit is "certified", I don't think it will wifi the ADSb "in" to your tablet.
The SkyBeacon does not have ADS-B “IN” capability. uAvionics SkySensor was made to go on the starboard wing to provide ADS-B in via wifi, unfortunately they did not proceed with TSO for those for Certified Aircraft..

Thank you all for your advice and ideas, they were very helpful. I bought the ADS-B unit today, after I called uAvionix with the serial number to verify it was legit.

Removed the antique aluminum C-172 wingtip, installed a ground wire, re-instelled the tip, and will be ready to mount the little bugger next time I get to the airport. The uAvionix unit comes with #6 machine screws to mount it, but my wingtip has solid riveted Tinnerman nut plates for P-K screws. So before I take the tip off and drill out the rivets... I'm gonna try to find some long Type B P-K screws and see if I can get it to fit without any more bloodshed.
