So, after being dissuaded by BEVANS to send another radio to them, I went searching. COST AERO was very nice to me, and offered to help me find a certified shop. Just did not work out.
I found ANOTHER place in Waco, Texas:
Ellison Avionics Services 4201 Lake Shore Drive Suite C Waco, Texas 76710
(254) 640-9024 EllisonAvionics@hot.rr.com
Called and talked to a Cynthia who was very nice.
DEAL: $525 flat shop rate + parts. So, we will see. Shipped it off last week.
10-12 week wait time, but they accepted it. I am good with that.
