Ditto what Viperdoc said. I'm also on the east coast (NJ) and feel it
is worth its worth in gold. Mine is mounted in my Beech Sundowner.

I'm thinking of adding the GTX 330 transponder to get traffic on my 430. Has
anyone done this and is it worth the price(what did it cost)? I fly mostly in
the eastern US and believe that there is pretty good coverage here.
