But-for the Garmin 430 IFR
authorization (STC??) to be IFR, the Lowrance product (and perhaps the
Garmin 295/395) is really just about as good. So far, the only
differance I can detect is the fact that the antenna is mounted on the
top of the plane, and less likely to loose lock on the satellites (Not
that this is a small issue).

Comments?

If terrain awareness is your main criteria, it does seem the handhelds do
provide more. Perhaps it is the fact that they are not under the same
scrutiny as the IFR certified GPS units that they are able to offer more
wizz-bang features.

In my case, my Garmin GNS430 is connected to an MX20 multifunction display.
This combination provides a poor man's TAWS, as there is a terrain database
in the MX20 and a terrain warning feature similar to the more expensive,
certified terrain warning devices that will flash man-made or natural
obstacles within a radius and altitude of the aircraft on the display.
