Bob,

I'd buy the Garmin TPX 330, with the thought of TRAFFIC.

Next best thing to TCAS, and in at least one way, better. It shows a
direction of flight line that TCAS does not. Of course, you'll also need a
430 to go with for display.

Narco? How do they stay in business. Their radios aren't heavy enough to be
anchors!

There has been talk of making Mode S a requirement sometime in the future.
Our transponder is giving trouble again. Does it make any sense to
consider
putting in a Mode S transponder now, if we have to replace ours? We can
get
a yellow-tagged Mode C transponder or even a new exchange from Narco
reasonably cheaply (for avionics, that is), but will it become a boat
anchor
when (if?) Mode S becomes a requirement. Thoughts?

Thanks
