Garmin's 327 is awesome. I bought one 4 years ago; no xponder worries
since.
I'll "second" Dan's endorsement of the GTX-327. I replaced an old
Narco transponder with the 327 several years ago, and we absolutely
love it.
Just check out how many new aircraft come with it as standard
equipment, and you'll see that Dan and I aren't alone in our
assessment.
