I'll admit to some lack of knowledge here but, other than the Mode S
ability of the Garmin 330, aren't xpdrs pretty much just a one trick
pony? I.e., they just receive a radar signal and reply. Why would a
Garmin 327 be any better than any other?


No cavity tube for one. Push button entry, VFR button, solid state
electronics...



Narco AT155 and AT165 are also solid state and have the push to squawk
VFR feature, as well as some timers. IIRC, the cost is quite a bit less
than the Garmin, and you can put it in your old tray.
