I am starting a build, and as life goes I am living under the Mode C veil of SAN.

So basically I have two choices. One, making it non-engine-driven-electrical and being exempted. Two, biting the bullet and getting a Mode-C transponder and an ADS-B. I guess in a busy airspace where we are, being seen offers some safety advantage, so I am looking at transponder/ADS-B solutions.

Now the question, what is the cheapest solution to satisfy the Mode-C and ADS-B requirement? Any ideas? How about a used Garmin 327 with an Uavionix echoUAT? All suggestions are appreciated.
